# Math Help - Integration!!!! Hard!!!

1. ## Integration!!!! Hard!!!

Ok so here is my problema...

Integral (1dx/asinx + bcosx + 1))

assume that a and b are constants...
I mean it could be IBP or Improper fraction... Or i dunno..

If anyone can solve this... I love you.

THanks.

Try the substitution

$x = 2 \tan^{-1} u$

3. hmmm honestly i get what you are saying but i don't see how it would help? I mean i've done trig subst. but none like that. After i subst. X then i don't know where to go...
