1.0 INTRODUCTION Differential Equation In Motion A differential equation is a mathematical equation that relates some functions of one or more variables with its derivatives. Besides that, differential equations differ from ordinary equations of mathematics in that in addition to variables and constants they also contain derivatives of one or more of the variables involved. The history of differential equations was independently invented by English physicist Isaac Newton (1642-1727) and German

for the number of cars passing between the intersections. a. If the traffic is to keep moving, at each intersection the number of cars entering per hour must equal the number of cars leaving per hour. Use this idea to set up a linear system of equations involving and b. Use Gaussian elimination to solve the system. c. If construction on 27th Avenue limits to 50 cars per hour, how many cars per hour must pass between the other intersections to keep traffic flowing? Solution a. Set up the system

Consistent System of Equations (determined): * For a given system, there exists one solution set for the different variables in the system or infinitely many sets of solution, so as long as we can find a solution for the system of equations, we refer to that system as being consistent. * For a two variable system of equations to be consistent the lines formed by the equations have to meet at some point or they have to be parallel. * For a three variable system of equations to be consistent

Bank of America had total liabilities of $1,898,945,000 at the end of the 12/31/2011 fiscal reporting year. The liabilities that represented this number included the non-interest bearing deposits, the interest bearing deposits, short term debt, other liabilities, federal funds purchased and securities sold and long term debt. The largest of Bank of America’s liabilities would be the interest bearing deposits while the lowest liability that Bank of America reported was the short term debt which means
