Homework Statement
Find the values of a,b & c so that
[tex]\lim_{x→0} \frac{ae^x-bcos(x)+ce^{-x}}{x\cdot sin(x)}=2[/tex]
Homework Equations
The Attempt at a Solution
The only thing which came to my mind is that when we put x=0, it should be a 0/0 form since the limit has a finite value. Therefore, a-b+c=0.
I can't think of any other equation to find the values of a,b and c.
