Question

Integration:

Answer 1

\[\LARGE \int~\frac{dx}{5+4cosx}\]

Answer 2

can I just call this a poopy problem and not try to do it?

Answer 3

Who told you to do it? lol

Answer 4

put \[\tan \frac{ x }{ 2 }=t,x=2~\tan^{-1} t,dx=\frac{ 2 }{ 1+t^2 }dt\]
\[\cos x=\frac{ 1-\tan ^2\frac{ x }{ 2 } }{ 1+\tan ^2\frac{ x }{ 2 } }\]
