11ok let me start
\int \frac{3 + 2cosx}{(2+3cosx)^2}dx
Hello ppl i have started this thread to approach integral Calculus
In this post you have to post integral probs.
Next question can only be posted after the first is answered so that it is easy for ppl to revise.
I would like this thread to go on and on until Jee 2010.
Pls actively participate.

1For any integral of the form a + bcos x/(b + asin x)2,
We hav the answer as, sin x/(b+a cos x).
For proof we can substitute t=sin x/(b+a cos x),find dt/dx n solving it further u get the answer as t.
Similarly, for integral of the form, a + b sin x/(b + a sin x)2, we have,
-(cos x)/(b + a sin x)
