Document Summary

**this is in no way indicative of the actual exam!!! These problems are just to test yourself with some problems that didn"t come out of the book. I"m just using miscellaneous exams from other universities. A few of them are strange or di cult. They"re intended mainly as thinking exercises - to think in di erent perspectives. *your best study materials are homeworks, quizzes, and hamid"s practice problems! (a) what is d. Here, f is a di erentiable function of 3 variables. F (t, 3t2, 5) = fx(t, 3t2, 5) 1 + fy(t, 3t2, 5) 6t. d dt (b) find the normal line to the surface (x + y)3 (y + z2)5 = 9 at the point (4,-2,1). We need to nd the gradient of this level surface f (x, y, z) = (x + y)3 (y + z2)5 = 9,
