Multivariable Calc Cheat Sheet - Check each line (0 x 5would give x=0. Check the corner points 2. Find and classify the critical points of the following functions: Substitute in for x and y. Web to a calc 1 type of min/max problem to solve. The following only apply only if a boundary is given 1. Compare this result to approaching. If point is de ned, limit exists. (a) f(x,y) = x5+y4−5x−32y+81 (b) f(x,y) = x3+y3+3xy−27 (c) f(x,y) = x2y+3xy−3x2−4x+2y+1 2.
