Trigonometric Expression Simplification: Solving Complex Sine and Cosine Problems

Math Problem Statement

sin(π - 3(α)) - cos(3π/2 + α) / (sin(π/2 + 3α) + cos(π + α)) / (1 + cos(π - 2α))

I see you uploaded a mathematical expression. Let me carefully analyze it and help you out.

The expression is:

{1 + \cos(\pi - 2\alpha)}$$ Now, let's break this down step by step to simplify it and understand its structure. Would you like me to proceed with simplifying it, or do you have specific steps you would like to focus on?

sin(A - B) = sin(A)cos(B) - cos(A)sin(B)
cos(A + B) = cos(A)cos(B) - sin(A)sin(B)
sin(A + B) = sin(A)cos(B) + cos(A)sin(B)
