Julian you left out a "^" on the RHS.
Going by Josh's handwritten version that's what he meant. If you go to the LaTeX test site
http://arachnoid.com/latex/ and paste in:
\int{\frac{e^{2x}}{{5+e^{2x}}}dx} \rightarrow \frac{\ln(5+e^{2x})}{2}
you'll get Julian's image - or something equivalent (commutative law).
