Let H be the hemisphere x2 + y2 + z2 = 66, z ≥ 0, and suppose f is a continuous function with f(4, 5, 5) = 5, f(4, −5, 5) = 11, f(−4, 5, 5) = 12, and f(−4, −5, 5) = 15. By dividing H into four patches, estimate the value below. (Round your answer to the nearest whole number.) H f(x, y, z) dS

The plane x+y+z= 24 intersects the cone x2+y2= z2 in an ellipse. The goal of this exercise is to find the two points on this ellipse that are closest to and furthest away from the xy-plane. Thus, we want to optimize F(x,y,z)= z, subject to the two constraints G(x,y,z)= x+y+z= 24 and H(x,y,z)= x2+y2-z2= 0.

Let S be the surface with equation x2+y2-z2=1. (a) In a single xy-plane, sketch and label the trace curves z=k for k = -2,-1,0,1,2. In words describe what types of curves these are and how they change. (b) In a single yz-plane, sketch and label the trace curves x=k for k= -2,-1,0,1,2. In other words, describe what types of curves these are and how they change as k varies.
