Question

how to integrate (1+cos2x)/(1-cos2x)

Answer 1

Look at how these relate to the power reduction formulae for sin and cos. In essence, simplify first.

Answer 2

hint :
1+cos2x = 2 cos^2 (x)
1-cos2x = 2 sin^2 (x)

Answer 3

yes after this we get tan^2(x)

Answer 4

cot^2 (x) not tan^2 (x)

Answer 5

No. It's the reciprocal of that

Answer 6

ok thanks a lot i got it , cot^2(x) = cosec^2(x) -1, then it is easy to integrate

Answer 7

obviously, yupz :)
