I was reading a statistics book, and part of the problem reduces to the calculus problem of doing the following:
1) Let u=x/y, v=y, with domain 0<x<y<1, how to find the ranges of u and v after the transformation?
2) Let u=x/(x+y), v=x+y with domain x>1, y>1, what values can u and v take on?
Is there a systematic way to do these?
Thank you for any help!
