Answer 2

The expression you've provided is a combination of trigonometric functions. Let's break it down step by step:

1. Cos(π/2 + α): This is the cosine of the angle formed by adding π/2 (90 degrees) to the angle α.

2. Sin(π - α): This is the sine of the angle formed by subtracting α from π (180 degrees).

Putting it all together, the expression can be written as:

Cos(π/2 + α) + Sin(π - α)

Depending on the value of α, this expression can be simplified further, and its numerical value can be calculated using trigonometric identities and properties. If you have a specific value for α, I can help you simplify or calculate the value of the expression.
