2) Obtain a solution for the following: a) xạy” – 4y = 0 b)xy” + y + xy = 0 c) xy” – (x+1)y' - y = 0
Suppose f(x,y)=xy(1−10x−4y)f(x,y)=xy(1−10x−4y). f(x,y)f(x,y) has 4 critical points. List them in increasing lexographic order. By that we mean that (x, y) comes before (z, w) if x<zx<z or if x=zx=z and y<wy<w. Also, determine whether the critical point a local maximum, a local minimim, or a saddle point.
