$(\sin \alpha-\cos \alpha)^2=$ (Simplify your answer.)

Question

Anonymous · Answer

The expression ( sin α − cos α ) 2 simplifies to 1 − sin ( 2 α ) by using the binomial expansion and the Pythagorean identity. The final result considers the double angle identity for sine as well. Thus, the answer has been simplified effectively.
