how do i solve for each function

 

In this mathematical problem, we are given specific conditions for angles α and β, and are required to evaluate trigonometric expressions based on these conditions:

1. **Given Conditions:**
   - \( \tan \alpha = -\frac{5}{12} \), with \( \frac{\pi}{2} < \alpha < \pi \).
   - \( \cos \beta = \frac{1}{2} \), with \( 0 < \beta < \frac{\pi}{2} \).

2. **Expressions to Evaluate:**
   - (a) \( \sin (\alpha + \beta) \)
   - (b) \( \cos (\alpha + \beta) \)
   - (c) \( \sin (\alpha - \beta) \)
   - (d) \( \tan (\alpha - \beta) \)

This setup involves determining the trigonometric values of the sum and difference of angles, leveraging identities such as the angle sum and difference formulas for sine, cosine, and tangent.

Students need to use the known values and conditions to find the precise trigonometric values for these expressions. This exercise is crucial for understanding trigonometric identities and their application in problem-solving.
