(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Integral: Upper limit is pie/3, lower limit is 0. secxtanx(square root of 1+secx)dx

Sorry if this is confusing, I dont know how to use the real math symbols.

3. The attempt at a solution

I realized it is U-substitution and not the FTC.

u=1+secx dx=sextanx du

when x=0, u=2 & x=pie/3, u=3.

I dont really know what to do after that, I'm a total noob at u-sub. Please help.
