Perform the multiplication and use the fundamental identities to simplify. (sinx-cosx)^2
~~~~~~~~~~~~~~~ 

(sinx-cosx)^2 = sin%5E2%28x%29+-+2%2Asin%28x%29%2Acos%28x%29+%2B+cos%5E2%28x%29 = %28sin%5E2%28x%29+%2B+cos%5E2%28x%29%29+-+2%2Asin%28x%29%2Acos%28x%29 = 


              = 1 - 2*sin(x)*cos(x) = 1 - sin(2x).    ANSWER

Solved.
