The region, D, defined by 1 <|z|<2 and 0 < Arg(z)< π/2.

What is the image of D under the map f(z) = z2 , g(z) = z3, and h(z)=1/z . Draw the picture of the images.

Hint: Writing z = re in polar form makes thing easier.

w = f(z) = z2. S = {z: Im(z) = b} . Find the image f(S). Draw a picture and explain what’s happening. Note that x = a and y = b intersect in one point, but their images under f(z) = z2 intersect in 2 points. How is this possible? Can you show that the images intersect perpendicularly?

Find an absolute max for the function f(x,y)=xy defined on the region D={(x,y)/ x^2/16+y^2<=1}. Do this problem two ways: first by finding the critical point(s) and parametrizing boundary and then, by using Lagrange multipliers. State what you learned about the Lagrange method from having these two sets of solutions.
