1. Introduction

1.1 Why choose Cambridge?
University of Cambridge International Examinations (CIE) is the world’s largest provider of international qualifications. Around 1.5 million students from 150 countries enter Cambridge examinations every year. What makes educators around the world choose Cambridge?

Recognition
A Cambridge International A or AS Level is recognized around the world by schools, universities and employers. The qualifications are accepted as proof of academic ability for entry to universities worldwide, though some courses do require specific subjects. Cambridge International A Levels typically take two years to complete and offer a flexible course of study that gives students the freedom to select subjects that are right for them. Cambridge International AS Levels often represent the first half of an A Level course but may also be taken as a freestanding qualification. They are accepted in all UK universities and carry half the weighting of an A Level. University course credit and advanced standing is often available for Cambridge International A/AS Levels in countries such as the USA and Canada. Learn more at www.cie.org.uk/recognition.

Support
CIE provides a world-class support service for teachers and exams officers. We offer a wide range of teacher materials to Centres, plus teacher training (online and face-to-face) and student support materials. Exams officers can trust in reliable, efficient administration of exams entry and excellent, personal support from CIE Customer Services. Learn more at www.cie.org.uk/teachers.

Excellence in education
Cambridge qualifications develop successful students. They build not only understanding and knowledge required for progression, but also learning and thinking skills that help students become independent learners and equip them for life.

Not-for-profit, part of the University of Cambridge
CIE is part of Cambridge Assessment, a not-for-profit organisation and part of the University of Cambridge. The needs of teachers and learners are at the core of what we do. CIE invests constantly in improving its qualifications and services. We draw upon education research in developing our qualifications.

1. Introduction

1.2 Why choose Cambridge International A Level Further Mathematics?
Cambridge International A Level Further Mathematics is accepted by universities and employers as proof of mathematical knowledge and understanding. Successful candidates gain lifelong skills, including: • • • • • a deeper understanding of mathematical principles; the further development of mathematical skills including the use of applications of mathematics in the context of everyday situations and in other subjects that they may be studying; the ability to analyse problems logically, recognising when and how a situation may be represented mathematically; the use of mathematics as a means of communication; a solid foundation for further study.

1.3 Cambridge Advanced International Certificate of Education (AICE)
Cambridge AICE is the group award of Cambridge International Advanced Supplementary Level and Advanced Level (AS Level and A Level). Cambridge AICE involves the selection of subjects from three curriculum groups – Mathematics and Science; Languages; Arts and Humanities. An A Level counts as a double-credit qualification and an AS Level as a single-credit qualification within the Cambridge AICE award framework. To be considered for an AICE Diploma, a candidate must earn the equivalent of six credits by passing a combination of examinations at either double credit or single credit, with at least one course coming from each of the three curriculum areas. The examinations are administered in May/June and October/November sessions each year. Further Mathematics (9231) falls into Group A, Mathematics and Sciences. Learn more about AICE at http://www.cie.org.uk/qualifications/academic/uppersec/aice.

7 Introduction 1. Additional information .

7 Guided learning hours .1
Advanced Level (‘A Level’) syllabuses are designed on the assumption that candidates have about 360 guided learning hours per subject over the duration of the course. (‘Guided learning hours’ include direct teaching and any other supervised or directed study time. They do not include private study by the candidate.) However, this figure is for guidance only, and the number of hours required may vary according to local curricular practice and the candidates’ prior experience of the subject.

7 Recommended prior learning .2
Knowledge of the syllabus for Pure Mathematics (units P1 and P3) in Mathematics 9709 is assumed for Paper 1, and candidates may need to apply such knowledge in answering questions. Knowledge of the syllabus for Mechanics units (M1 and M2) and Probability and Statistics units (S1 and S2) in Mathematics 9709 is assumed for Paper 2. Candidates may need to apply such knowledge in answering questions; harder questions on those units may also be set.

7 Progression .3
Cambridge International A Level Further Mathematics provides a suitable foundation for the study of Mathematics or related courses in higher education.

7 Component codes .4
Because of local variations, in some cases component codes will be different in instructions about making entries for examinations and timetables from those printed in this syllabus, but the component names will be unchanged to make identification straightforward.

7 Grading and reporting .5
A Level results are shown by one of the grades A*, A, B, C, D or E indicating the standard achieved, Grade A* being the highest and Grade E the lowest. ‘Ungraded’ indicates that the candidate has failed to reach the standard required for a pass at A Level. ‘Ungraded’ will be reported on the statement of results but not on the certificate.

7 Introduction 1. Additional information .

Percentage uniform marks are also provided on each candidate’s statement of results to supplement their grade for a syllabus. They are determined in this way: • A candidate who obtains… … the minimum mark necessary for a Grade A* obtains a percentage uniform mark of 90%. … the minimum mark necessary for a Grade A obtains a percentage uniform mark of 80%. … the minimum mark necessary for a Grade B obtains a percentage uniform mark of 70%. … the minimum mark necessary for a Grade C obtains a percentage uniform mark of 60%. … the minimum mark necessary for a Grade D obtains a percentage uniform mark of 50%. … the minimum mark necessary for a Grade E obtains a percentage uniform mark of 40%. … no marks receives a percentage uniform mark of 0%. Candidates whose mark is none of the above receive a percentage mark in between those stated according to the position of their mark in relation to the grade ‘thresholds’ (i.e. the minimum mark for obtaining a grade). For example, a candidate whose mark is halfway between the minimum for a Grade C and the minimum for a Grade D (and whose grade is therefore D) receives a percentage uniform mark of 55%. The uniform percentage mark is stated at syllabus level only. It is not the same as the ‘raw’ mark obtained by the candidate, since it depends on the position of the grade thresholds (which may vary from one session to another and from one subject to another) and it has been turned into a percentage.

7 Resources .6
Copies of syllabuses, the most recent question papers and Principal Examiners’ reports for teachers are available on the Syllabus and Support Materials CD-ROM, which is sent to all CIE Centres. Resources are also listed on CIE’s public website at www.cie.org.uk. Please visit this site on a regular basis as the Resource lists are updated through the year.

North America, Asia Pacific and Latin America confectionery markets have also maintained increasing sales of these products despite the global economic downturn. The recession has caused many consumers to sacrifice volume rather than quality, and to use confectionery as a reward or as a means to help alleviate stress. However, sugarized gum, milk chocolate tablets and boiled sweets confectionery are all being adversely affected by mounting consumer health concerns. Obesity and diabetes are major health issues that are increasingly affecting both the young and aging populations. In particular, the United States (U.S.), United Kingdom (U.K.), and Japan will stand to benefit the most from reduced calorie and low/no/reduced sugar content. When it comes to “healthy” confectionery, consumers tend to look for products benefiting dental and cardiovascular health, as well as low-calorie products that help assuage guilt over indulgence. We see this trend playing out with sugar-free gum which has been performing well globally, and is predicted to continue, particularly in emerging countries. Gum is...

Chocolate

...Chocolate i/ˈtʃɒklət/ is a raw or processed food produced from the seed of the tropical Theobroma cacao tree. Cacao has been cultivated for at least three millennia in Mexico, Central America and Northern South America. Its earliest documented use is around 1100 BC. The majority of the Mesoamerican people made chocolate beverages, including the Aztecs, who made it into a beverage known as xocolātl [ʃo'kolaːt͡ɬ], a Nahuatl word meaning "bitter water". The seeds of the cacao tree have an intense bitter taste, and must be fermented to develop the flavor. After fermentation, the beans are dried, then cleaned, and then roasted, and the shell is removed to produce cacao nibs. The nibs are then ground to cocoa mass, pure chocolate in rough form. Because this cocoa mass usually is liquefied then molded with or without other ingredients, it is called chocolate liquor. The liquor also may be processed into two components: cocoa solids and cocoa butter. Unsweetened baking chocolate (bitter chocolate) contains primarily cocoa solids and cocoa butter in varying proportions. Much of the chocolate consumed today is in the form of sweet chocolate, combining cocoa solids, cocoa butter or other fat, and sugar. Milk chocolate is sweet chocolate that additionally contains milk powder or condensed milk. White chocolate contains cocoa butter, sugar, and milk but no cocoa solids. Cocoa solids contain alkaloids such as theobromine and phenethylamine, which have physiological effects on the body. It...

Chocolate

...The trends that could transform the chocolate industry kpmg.com T he outlook for the world’s chocolate industry is brighter than it has been for eight years. Euromonitor predicts the industry will enjoy a 6% rise in revenues in 2014, delivering record global revenues of US$117bn. This robust performance is driven by a 2.1% increase in volume, reflecting growing appetite for chocolate in emerging markets. The challenge for the industry’s major players is how to make best use of this boom to profitably grow their volumes faster than the markets, achieve sustainable improvements in core operating margins and make the right investments – be they in capacity, acquisitions, the supply chain, marketing or R&D – to seize the significant opportunities ahead. The single biggest factor improving the industry’s performance is the fact that, at long last, the global economy is showing signs of sustained recovery. Growth in many major markets is accelerating. The stellar performers are India (expected to grow by 22% this year), Brazil (13%) and China (11%). The potential long-term growth in emerging economies – many of which have growing middle classes – is vast. To give just one example: the per capita consumption of chocolate in China is only a tenth of that in Switzerland. Yet, as this global tour of the chocolate industry suggests, the future is not without challenges. The immediate concern is the balance between supply of cocoa and the chocolate industry’s demand. Manufacturers are...

...INTRODUCTION The purpose of this research report is to gain knowledge on chocolate and give an insight on its history, production and various types used for cooking and commercial uses. Moreover, proper understandings of how the different types of chocolate are being processed. Chocolate is a well-known confection produced from cocoa beans. It is popular worldwide, having diverse tastes; sweet and bitter. Chocolates are generally expensive, however of very high demand. It is used rarely in homes for cooking; most people simply purchase the product as a snack. Food and beverage outlets are mainly involved in the usage of chocolate for cooking. There are certain facts derived after the observation of chocolate consumption around the globe. It is noted that Europe dominates the market by holding 16 out of the top 20 chocolate consumers. Furthermore, Americans consumed approximately 3 billion pounds of chocolate in 2001. Chocolate was mostly consumed in between meals and it is found that the winter season brings an increase in the demand for chocolate HISTORY OF CHOCOLATE The Pre-Columbian Experience 1200 B.C. — 1492 A.D.  The history of chocolate dates back to at least 4000 years and it is found that monkeys made the spectacular discovery of the cacao plant.

Sobe Chocolate

...[pic] introduction Since its inception, SoBe has branded products that are considered an alternative to conventional market offerings. Originally a beverage company that introduced a line of performance enhanced teas which included special additives such as ginseng and panax, the brand’s edgy persona has been extended to fruity energy drinks, sports drinks, chewing gum, soda, and, most recently, chocolate. Extending the SoBe brand image to performance enhanced chocolate has proven challenging. The SoBe Chocolate group (operating in conjunction with HVC Lizard Chocolate) has tried, with some success, to create a new confections category centered on the concept of functional indulgence. Yet, the product line suffers an identity crisis with consumers who are not used to the inclusion of performance enhancers in chocolate. Initial packaging and marketing efforts have not adequately educated the market and consumers are not associating the SoBe brand identity with a chocolate bar, or SoBe Chocolate to the confections category. Situation The Life and Times of SoBe SoBe came to life in 1996 as the South Beach (SoBe) Beverage Company. Founded by two Pepsi alums, Mike Schott and John Bello, the company introduced a beverage line that “defied convention”. The attitude at SoBe is characterized by the following from John Bello: “Mike and I came from Pepsi, where things get massaged into mediocrity.

Ethel’s Chocolate Lounge is a restaurant with gourmet chocolates where consumers could relax. This lounge was trying to be like a Starbucks. They wanted to sell gourmet chocolates for decent prices. The best type of consuming decision that best describes the choice to indulge at Ethel’s would be to use the extensive decision making. Extensive decision making is the most complex type of consumer decision making when buying an unfamiliar, expensive product (Lamb, Hair, McDaniel, 2010, p.80). Because Ethel’s Chocolate Lounge provided great quality for consumers, they have a higher level of interest in indulging at Ethel’s. John wanted to maintain Ethel’s special treats, so he continued to make affordable gourmet chocolates. “In our extensive consumer research, women told us they wanted an approachable place to select, purchase, and hangout and enjoy chocolate more frequently. And they said they were tired of mystery middles; where chocolate pieces are tossed off after one bite because the centers aren’t expected. That’s why we created the Ethel’s brand, which includes the first ever approachable gourmet chocolate for everyday and our chocolate lounges,” says John Haugh, president of Ethel’s (chocolateatlas, 2012).

...JOY OF CHOCOLATE J.O.C. (Joy of Chocolate) was created in 1999 by Suzy Campbell and is based in Stirling. She funded her new business with her redundancy package from Safeway Stores where she had been General Manager. Suzy’s motivation was to fulfil her ambition of having her own business and achieve her dream of creating gourmet chocolates. In the five years prior to her redundancy Suzy had spent her holidays achieving professional qualifications in chocolate making and before starting the business she had spent six months gaining valuable work experience with various chocolate firms in Europe. In the early days Suzy considered survival a major achievement but as time passed her ambitions for the business grew. Suzy’s career in retailing had given her valuable managerial experience. She was skilled in forward planning and had sales expertise developed through the years working with food suppliers. Suzy believed that existing chocolate suppliers focused on importing a finished product rather than developing their own goods. Suzy quickly realised that there was a niche in the market supplying a wider range of gourmet chocolates to business customers. To penetrate this market Suzy had firstly, targeted luxury restaurants and hotels with gourmet chocolates for their guests and secondly she approached organisations offering to supply them with corporate gifts.
