Homework Statement
Let [tex] f(x,y) = (x^2 - y^2, 2xy) [/tex] where f is defined on the open set [tex] A = \{ (x,y) \in \mathbb{R}^2 : x > 0 \} [/tex].
What is the set f(A)?
Homework Equations
The Attempt at a Solution
I'm guessing they're asking me to describe f(A) using set notation. But I don't know how to do this. I've tried plotting a set of points to get an idea what f(A) would look like on the plane, but I can't get any idea whatsoever.
Any help or ideas?
