Hi i am completely stuck on a intergration problem, i have tried substition, and every technique i can think off but i cannot solve it. It is a improper intergral and the answer is pie/4(adsbygoogle = window.adsbygoogle || []).push({});

The question is:

find the intergral with limits upper pie/2 and lower 0

1/(1+(tanx)^sqaureroot pie).dx

P.S: how do i type equations liek the way some ppl do in their threads
