Put the values alpha and Beta in place of (alpha+beta) to obtain 2 eqns. Subtract them to form an eqn and then obtain the relation between 1 and 2 (consider only principle soln.)
From the above eqn,., firstly, a relation between 1 and 2 will be obtained. Also, a relation between 1,2and 1,2 will be obtained,
Use Cos 2x= (1-tan2x)/(1+tan2x) or any identity to get ahead and arrive at the desired result.
