Hello guys this problem is come when i solved one of my physics homeworks. I solved the physical part of the problem but then i stucked on some trigonometric trick i probably don't know and i cant get the finale result. They have got.
I attached photographs of the full solving please just ignore the physics part and help me with the last step of solving when is written. "It's Should be"
By the way i plug some numbers into the first form and the second form of the answer and i get the same value so the answer itself is definitely correct the problem is only in trigonometric identities.
