Hello folks. I'm a 2nd year Physics major from from South Africa. Looking forward to being part of the community.

Homework Statement Given f(x,y)=(y+x)/(y-x) use an ε-∂ proof to show that lim(x,y)→(0,1) f(x,y) exists. Homework Equations |(y+x)/(y-x)-1|=|(2x)/(y-x)| The Attempt at a Solution I know that the limit is 1. I can't figure out how to massage the above any further to get it into the form...
