You don't include any instructions within your post. What are you supposed to be doing with this equation? It cannot be solved (having two variables in just one equation). Are you perhaps needing to determine if this equation is an identity?

Either way, when you reply, please include a clear statement of your efforts so far, such as how you applied the angle-difference identity to the left-hand side. Thank you!
