What does your textbook say about (iv) ∫ cosec?
= log cosec – cot + C We have cosec (cosec cot ) cosec (cosec cot ) Put cosec x + cot x = t so that – cosec x (cosec x + cot x ) dx = dt So cosec –log | | – log |cosec cot | cosec cot – log cosec cot = log cosec cot x + Example Find the following integrals: sin ( (iii) Solution We have (sin ) ( – cos ) cos (sin ) Put t = cos x so that dt = – sin x dx
