... Clearing Fractions and Decimals from an equation If given a choice, most of us would rather work a problem in whole numbers rather than fractions or decimals. We’re going to look at a little gimmick that will “clear the factions” from an equations. We’re going to look at lots of examples. (It’s alwa ...

... - The contents of the function DivDiv.m looks lengthy but it is so only to account for the fact that the code assumes diffusivity (x,y) - dependent. The function solveTemperature.m applies the 4th order Runge-Kutta method (for better stability than Euler) to evaluate dT several times and finally acc ...

... z = −1 − 2 3(x − π/3) − 3y. (2) Find all points on the surface z = x2 − 2xy − y 2 − 8x + 4y, where the tangent plane is horizontal. Solution: The tanget plane being horizontal implies n =< −fx , −fy , 1 >=< 0, 0, 1 >. This means that fx = 0 and fy = 0. Creating these equations, fx = 2x − 2y − 8 = 0 ...
