= integ (1 - 2 sin2x / sinx
seperating these 2 we get
I = (dx / (sinx(cos2x - sin2x)1/2) - 2 (sinx / (2cos2x - 1)1/2)
= (cosec2x / (cot2x - 1)1/2) - (2/root2) (sinx/(cos2x - (1/2)1/2))
take cot x = a cos x = b and solve u will get the answer....
(p.s-> formula editor not working of slow speed...soo...manage...plzz).
