Answer 2

Let's simplify the expression:

4sin(π/2 + x) + cos(π + x) + sin(π - x)

First, let's use the trigonometric identities:

1. sin(π/2 + x) = cos(x)
2. cos(π + x) = -cos(x)
3. sin(π - x) = sin(x)

Now, substitute these identities back into the expression:

4cos(x) - cos(x) + sin(x)

Now, simplify further:

(4cos(x) - cos(x)) + sin(x)

Combine like terms:

3cos(x) + sin(x)

So, the simplified expression is:

3cos(x) + sin(x)
