Expert Answer
Breaking the given function, we get
1/ sinx (1+cosx) + 1/1+cosx = F + G
The function G can easily be integrated by using the formula 1 + cosx = 2 cos2x/2
Now, let's see how to integrate the function F.
Put cosx = t so that -sinx dx = dt
Thus, we get
This integral can now be easily evaluated.
