1. The problem statement, all variables and given/known data Let f:R^2 to R^2 be defined by f(r,theta) = (rcos(theta), rsin(theta)) Sketch the image under f of the set S = (1,2) X (0,pi) (The open brackets should be closed brackets but Im on a foreign keyboard and cant figure out how to get closed brackets). 2. Relevant equations Unsure 3. The attempt at a solution I am unsure how to sketch something going from R^n to R^m in general, so I have no attempt at a solution. Any hints would be greatly appreciated.
