i tried it..........rearranging......but no use......i also manipulated it differentely to use integration by parts...........also converted it to sin&cos......and used defactorization formulas....but its going too complicated.......and integral calculators are also not ansring.......

TopNewestNot possible to have an elementary close form. Think of \(\tan(A+B) = \frac{\tan A + \tan B}{1 - \tan A \tan B} \).

That's why I said there's no closed form. You need to use elliptic integrals to solve it.
