Answer 2

It appears you have a trigonometric expression involving the sine and cosine functions. I'll simplify it for you step by step:

sin(x)cos(p/4) - cos(x)sin(p/4)

You can use the angle sum formula for sine to simplify this expression:

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

In this case, A = x and B = p/4, so:

sin(x - p/4)

So, the simplified expression is sin(x - p/4).
