I was given the following problem which I thought I knew how to solve. The only problem is that the answer I got was not given as an option for an answer. It doesn't seem to be equivalent either. It must be that I went wrong somewhere - where though? This is the problem and my steps:
[MATH]\int\frac{\cos(x)}{e^{2\sin(x)}+4e^{\sin(x)}+4}\ dx[/MATH]
[MATH]\int\frac{\cos(x)}{e^{2\sin(x)}+4e^{\sin(x)}+4}\ dx[/MATH]
