Proving identities

If sin(26)+sin(24)=Sin(A), 0<A<90, then A=____ degrees.

I know this is with the sum-to-product identity, but I need help with the steps.

show that 1/(1-cos x) - 1/(1+cos x)=2cosec x cot x

show that 1/(1-cos x) - 1/(1+cos x)=2cosec x cot x

Find the exact value of cos 15 degrees= sqrt(A)(sqrt(B)+1)/4...what is A and what is B?

I know how to get the answer, but for some reason, they want it in this format and I'm not sure how to do it this way.

There are 2 possible answers I can choose from. Either Bounded or Continuous

Determine A, B and C so that the formula (cosx−5sinx)^2 = A cos2x + B sin2x + C is valid for all values on x. A, B och C are integers.

This is translated from a trigonometry problem in another language, I hope you understand it.
