If (cos^(3) theta )/( (1- sin theta ))+...

If ` (cos^(3) theta )/( (1- sin theta ))+( sin^(3) theta )/( (1+ cos theta ))=1+ cos theta `, then number of possible values of ` theta ` is ( where ` theta in [0,2pi]`)

Verified by Experts

The correct Answer is:

`theta = (pi)/(2)` which is not possible.
