Chapter 4, Problem 26(choose chapter or problem)
Sometimes it can be difficult to determine the critical point of a function f because the system of equations that arises from setting f equal to zero may be very complicated to solve by hand. For the functions given in Exercises 2427, (a) use a computer to assist you in identifying all the critical points of the given function f , and (b) use a computer to construct the Hessian matrix and determine the nature of the critical points found in part (a).f (x, y,z) = yz xyz x 2 y2 2z2
