Question

integration of this

Answer 1

First apply formula for a cube + b cube I the denominator.
A cube + b cube is (a+b) (a square + Bsquare +ab)

Take tanx common from numerator and after taking common 1+tan square x will be cancelled from the eqn.

Now in denominator quadratic will form in terms of tanx and a tanx will be there in numerator also.
I hope that after this you will be able to do the next steps.

Hope you get your answer.
