Pooja Bhakar 6 years, 3 months ago

Firstly we put cosx=cos^2 x/2-sin^2 x/2 and sinx = 2sinx/2cosx/2 then dividing numerator and denominator by cos^2 x/2 then we get the result in form of sec and tan after that put tanx/2=t so that 1/2sec^2 x/2dx=dt i.e. sec^2 x/2 = 2dt then solve it by partially method .
