Problem 77E
Parametrized Surfaces Just as you describe curves in the plane parametrically with a pair of equations Many computer algebra systems permit you to plot such surfaces in parametric mode. (Parametrized surfaces are discussed in detail in Section 16.5.) Use a CAS to plot the surfaces in Exercises . Also plot several level curves in the xy-plane
