Question 1191732
.
Perform the multiplication and use the fundamental identities to simplify. (sinx-cosx)^2
~~~~~~~~~~~~~~~


<pre>
(sinx-cosx)^2 = {{{sin^2(x) - 2*sin(x)*cos(x) + cos^2(x)}}} = {{{(sin^2(x) + cos^2(x)) - 2*sin(x)*cos(x)}}} = 


              = 1 - 2*sin(x)*cos(x) = 1 - sin(2x).    <U>ANSWER</U>
