Question

Help please?

find the indefinite integral and check the result by differentiation. integrate (cos x / 1-cos^2 x) dx

Answer 1

@ganeshie8 could you help me with this one please?

Answer 2

simplify denominator first...
use below identity :
sin^2x + cos^2x = 1

Answer 3

integral (cos x/sin ^2 x)dx
put sin x=t
cosx dx=dt

Answer 4

you may do that,
or after simplification if u remember the derivative of csc x, that works too...
pen down and start messing wid it a bit :)

Answer 5

I got a little confused.. just to make sure the integral becomes (cos x/ sin^2 x) dx right?

Answer 6

thats right
