I got the following problem in my math class:(adsbygoogle = window.adsbygoogle || []).push({});

http://img81.imageshack.us/img81/7508/limitdv4.jpg [Broken]

I know that I'm supposed to use L'Hopital's rule, but I have 2 problems. First of all, I don't know how to make that into a fraction, besides putting it all over 1 or making tan negative and putting it under 1. Also, I have no idea how to even find the derivative of that mess.

I know that the answer is e^(2/pi), but I'd like to know how to get it.

Can anybody help me, please?
