Today we will discuss about the Cartesian coordinate system. It is a coordinate plane that is formed when a vertical scale or the y-axis goes through a horizontal scale or the x-axis that defines each point in a plane. The point in which the x-axis and y-axis meet is known as the origin or zero. The two axes divide the plane into four areas called quadrants. The top- right is the first quadrant and it continues counterclockwise in order. The Cartesian coordinate system was developed in 1637 by a French mathematician and philosopher Rene Descartes who noticed a fly crawling around on the ceiling. He watched the fly for a long time. He wanted to know how to tell someone else where the fly was. Finally he realized that he could describe the position of the fly by its distance from the walls of the room. When he got out of bed, Descartes wrote down what he had discovered. Then he tried describing the positions of points, the same way he described the position of the fly. His discovery would help paved the way for more analytical geometry. The discovery of the Cartesian coordinate system has revolutionized mathematics by providing a link between algebra and geometry. It is the foundation for analytical geometry which uses the principals of algebra and analysis. For example every point on a coordinate plane has a set of coordinates which is input (x value) and the output the (y value) known as order pairs. We can draw a line on a coordinate plane using two or more points. In analytic geometry you can find the distances between you are able to gather information about the line and write an equation of it. Usually the Cartesian coordinate system is applied to gather equations lines, shapes and three-dimensional figures. The Cartesian system can be used for three dimensional spaces as well. The three-dimensional representation is a triplet of perpendicular lines that intersect at the origin. The third line is known as the z-axis. The discovery of the Cartesian coordinate system has revolutionized mathematics by providing a link between algebra and geometry. It is the foundation for analytical geometry which uses the principals of algebra and geometry. In modern times, The Cartesian coordinate system is used in architecture, maps, coding for graphics, etc. Longitude and Latitude is based upon the coordinate system where any point in the world can be defined as by a pair of coordinates. The x-axis is represented by the equator and the y-axis is represented by the prime meridian the distance between any two places can be calculated using this coordinate system which organizes and easily pinpoint any location with greater accuracy. Many amazing architecture and construction used the coordinate system to map out geometric shapes used to assemble complex structures. When building structures such as bridges, tunnels, and highways architects must first draw out the design on a coordinate plane and find the dimensions of the building before any construction can be attempted. The coordinate system is important when coding software or constructing graphics on a computer or mobile device. Grids keep things organizes while helping to make 3D graphics on software. Programmers use the three-dimensional coordinate planes to design their graphic and use algebra to find out dimensions of their 3D graphic. Thus the coordinate systems keep things organized and neat.

In mathematics, a real number is a value that represents a quantity along a continuous line. The real numbers include all the rational numbers, such as the integer – 5 and the fraction 4/3, and all the irrational numbers such as positive square root of 2,√2. Real numbers can be thought of as points on an infinitely long number line. In basic mathematics, a number line is a picture of a straight line on which every point is assumed to correspond to a real number and every real number to a point. Often the integers are shown as specially-marked points evenly spaced on the line. Although this image only shows the integers from −9 to 9, the line includes all real numbers, continuing forever in each direction, as shown by the arrows and also numbers not...

The Cartesian Plane

...Before the end of the European Renaissance, math was cleanly divided into the two separate subjects of geometry and algebra. You didn't use algebraic equations in geometry, and you didn't draw any pictures in algebra. Then, around 1637, a French guy named René Descartes (pronounced "ray-NAY day-CART") came up with a way to put these two subjects together. Rene Descartes was born on March 31, 1596, in Touraine, France. He was entered into Jesuit College at the age of eight, where he studied for about eight years. Although he studied the classics, logic and philosophy, Descartes only found mathematics to be satisfactory in reaching the truth of the science of nature. He then received a law degree in 1616. Thereafter, Descartes chose to join the army and served from 1617-1621. Descartes resigned from the army and traveled extensively for five years. During this period, he continued studying pure mathematics. Finally, in 1628, he devoted his life to seeking the truth about the science of nature. At that point, he moved to Holland and remained there for twenty years, dedicating his time to philosophy and mathematics. During this time, Descartes had his work "Meditations on First Philosophy" published. It was in this work that he introduced the famous phrase "I think, therefore I am." Descartes hoped to use this statement to find truth by the use of reason. He sought to take complex ideas and break them down into simpler ones that were clear. Descartes believed that mathematics...

Magnet Theory

...Proc. CERN Accelerator School on Measurement and Alignment of Accelerator and Detector Magnets, April 11-17, 1997, Anacapri, Italy, CERN-98-05, pp.1-26 BASIC THEORY OF MAGNETS Animesh K. Jain RHIC Project, Brookhaven National Laboratory, Upton, New York 11973-5000, USA Abstract The description of two dimensional magnetic fields of magnets used in accelerators is discussed in terms of a harmonic expansion. The expansion is derived for cylindrical components and extended to Cartesian components. The Cartesian components are also described in terms of a complex field. The rules for transformation of the expansion coefficients under various types of coordinate transformation are given. The relationship between a given current distribution and the resulting field harmonics is explored in terms of the vector and complex potentials. Explicit results are presented for some simple geometries. Finally, the harmonics allowed under various symmetries in the magnet current are discussed. 1. MULTIPOLE EXPANSION OF A TWO-DIMENSIONAL FIELD For most practical purposes related to magnetic measurements in an accelerator magnet, one is interested in the magnetic field in the aperture of the magnet, which is in vacuum and carries no current. Also, most accelerator magnets tend to be long compared to their aperture. Thus, a two dimensional description is valid for most of the magnet, except at the ends. We shall at first confine ourselves to a description of a purely two dimensional...

...referring to lines which radiate from (or intersect at) a radio antenna. The use of the radial method is more common in North America where the FCC and CRTC use it in Mediumwave transmission planning and regulation. In Europe and Asia, the use of radials has fallen out of favor since the 1970s and in many nations the radial antenna proof is only acceptable as an ancillary antenna proof. Canada and Mexico, due to lower population densities never implemented the fully complete radial models that the US FCC did. The radial method has been falling out of favor for methods based on Cartesian coordinates. Cartesian methods require more CPU time (and memory) to compute, but are understood to more realistically represent antenna systems.

Descartes and Heidegger

...Descartes and Heidegger both set a new standard for thinking, but at completely different ends. Descartes says a subject is a thinking thing that is not extended, and the object is an extended thing which does not think. Heidegger rejects this distinction between subject and object by arguing that there is no subject distinct from the external world of things because Dasein is essentially Being-in-the-world. To Heidegger, everything has an essence, yet that essence is concealed to humans. Descartes’s philosophy placed a heavy emphasis on deductive reasoning and mathematics. He developed analytic geometry and the Cartesian coordinate system which helped scientists use mathematics to model the physical world. One of his influences on today’s world is his philosophy of mind, dualism, where the mind is a nonphysical substance. Descartes proposed that reality consists of two separate realms: a physical realm and a mental realm. The physical realm is the realm of matter and energy. Its properties can be measured and studied by science. Everything in this realm operates only by mechanical properties. Descartes included the body as part of the physical realm, viewing it as a biological machine with no free will. Descartes’s view that the body is a machine has led a mechanical approach in medicine, because Descartes views technology as separate from ethics. This idea is prevalent in today’s philosophy – computer science majors are not required to take a morality course. This means...

Algebra Strategies (Not Mine)

...Algebra I Suggested Teaching Strategies The curriculum guide is a set of suggested teaching strategies designed to be only a starting point for innovative teaching. The teaching strategies are optional, not mandatory. A teaching strategy in this guide could be a task, activity, or suggested method that is part of an instructional unit. It should not be considered sufficient to teach the competency and the associated objective(s); the teaching strategy could be one small component of the unit. There may not be enough instructional time to utilize every strategy in the curriculum guide. The 2007 Mississippi Mathematics Framework Revised includes the Depthof-Knowledge (DOK) level for each objective. As closely as possible, each strategy addresses the DOK level specified for that objective or a higher level. Suggestions or techniques for increasing the level of thinking may be included in the strategy(ies). In addition, the process strands (problem solving, communication, connections, reasoning and proof, and representation) are included in the strategies. The purpose of the suggested teaching strategies is to assist school districts and teachers in the development of possible methods of organizing the competencies and objectives to be taught. Since the competencies and objectives require multiple assessment methods, some assessment ideas may be included in the strategy.

By their very nature, clinical trials generate a large amount of information, and a concise visual presentation of the results is essential. Information about the patient population, drug dosages, clinical responses, and adverse events must be clear. Clinical laboratory results need to be presented within the context of acceptable limits, and subtle changes over time must be highlighted. This presentation will show, by example, how such graphs can easily be created using the SAS/GRAPH® SG procedures. The techniques that will be emphasized in this presentation include: • • • • • • Creation of a dose response plot by overlaying multiple plots in one graph Construction of a hematology panel using treatment regimen and visit numbers as the classification variables Presentation of a matrix of liver function tests (LFTs) for at-risk patients Aggregation of data into on-the-fly classification variables using user-defined formats Getting the axis you want using built-in best fit algorithms Generation of publication-ready graphs in color and in black and white INTRODUCTION The new SAS/GRAPH procedures—SGPLOT, SGPANEL, and SGSCATTER—provide new tools for viewing and reporting data collected during clinical trials.

Wellness

...Wellness is the integration of states of physical, mental and spiritual well-being. Wellness is composed of seven dimensions that include social, emotional, spiritual, environmental, vocational, intellectual and physical wellness. Each of these dimensions act and interact in a way that contributes to own quality of life. Some of the dimensions of wellness in my life I value higher than other, but I also value some very closely. Also, at times many of these are interconnected with one another. The dimension that I value the highest is spiritual wellness. My family has always stressed upon following the Catholic way of life and having good morals and values. The three other dimensions of wellness that I value very similarly are intellectual, physical and social wellness. I am always willing and excited to learn new concepts, improve skills and seek challenges that will allow me to become a great future Health and Physical Education teacher. As a competitive runner for Rowan University, living a healthy lifestyle and having high physical fitness are vital in order to be a successful.

...Math Investigation Transformation of graphs A.1:By looking at the different graphs we can observe the effects of k in the function. In the graphs acts on the y-axis, by the changing the value of k the y axis goes down or up, it’s a vertical translation. When the value is positive the parabola goes up and when is negative it goes down. In the first graph when K is 4 it moves four spaces up in the y axis and the second one when K is -3 it moves three spaces down. Although the line moves the curve is not affected, this means that the gradient is not affected. A.2: My observations from last exercise apply to this graphs. The value of k is still a constant so the line keeps moving the y axis upwards or downwards depending on the value , it doesn’t move through the x axis , this means that the gradient never changes. A.3:Generalisation When ever the value of K is a constant it will only affect the line on the y axis .Theres a vertical translation on the line, when the value is positive it moves upwards and when is negative it moves dowards from the original line.The cruve of the line never changes this in other words mean that the gradient stays the same and the line don’t moves through the x axis.

...How do you differentiate between an expression and an equation? Provide an example of each, where the two are either related to or similar to each other. (6/26) The major difference between an equation and an expression is that while an equation has to be solved, an expression does not. For instance, this is an equation: 3x + 1 = 5.if x is multiplied by 3 and add 1, the result will be a 5. In similar vein, an equation consists of two expressions connected by an equals sign. It can only be true or false (Miller, 2009). The primary difference between the two is an equal sign. References: Miller, M. (2009). Algebra: Book 3. Eugene, OR: Garlic Press. Answer to Nathan: (6/26) Hi Nathan, I agree with you when you say "an expression is a mathematical "phrase". " In most cases it stands for a single element. 3x + 1 is an example of an expression. The expression means that its value three times the value of x, plus 1. An expression can also be a single number or variable, since those have a numerical value. Unlike in the case of an equation, an expression is never true or false, but just has a numerical value. Are the properties used to solve inequalities the same as those used to solve equations? Explain your answer. (6/27) The properties to solve inequalities are NOT exactly the same as the properties to solve equations. But, the properties to solve equations ARE exactly like those used to solve inequalities. Inequalities have an exclusive property while solving because of...
