Hi
Please follow the steps to reach to the solution.
Convert all terms into COS. Form a quadratic in COS and then find its roots. You will see that one of the roots will be grater than 1 which is not possible.
Now the no of solutions will depend upon the given interval of x. In ( 0 to 2pi ) we have 2 solutions.
