find the image of the set S under the given transformation: S is the disk given by u^2 + v^2 <= 1 where x=au, y=bv(adsbygoogle = window.adsbygoogle || []).push({});

since it is a circle i have that the boundaries are [-1,1] x [-1.1] so for my equations i got

x = au, y = -b

x = a, y = bv

x = au, y = b

x = -a, y = bv

i don't know what the next step would be in trying to draw that
