1. The problem statement, all variables and given/known data How do I prove the function ((2^x)-1)sin(y))/(xy) converges to ln(2) in the case of x=0 and y=0..? 2. Relevant equations 3. The attempt at a solution Yeah I'm trying to figure out where to start honestly... I know i'm not suppose to post unless I have a real attempt at the solution.. I could BS something but anyone wanna point me in the right direction? Squeeze Theorem? Is there some key property I should be aware of?
