Don't forget what you learned about dividing by a fraction!=sin(x)cos(x)+cos(x)sin(x)2
I can get there, easy
But I'm not sure how they get the following:
=cos2(x)+sin2(x)2cos(x)sin(x)
=sin(x)cos(x)+cos(x)sin(x)2
I can get there, easy
But I'm not sure how they get the following:
=cos2(x)+sin2(x)2cos(x)sin(x)
