SOLUTION: Verify the identity (sinx + cosx)^2=1 + sin2x
You can put this solution on YOUR website! Verify the identity --1. Expand the left hand side of the equation 2. simplify this result--now you need to utilize the property of Sin(a+b)=sin(a)*cos(b)+sin(b)*cos(a)--Sin(2x)=sin(x+x)=sin(x)cos(x)+sin(x)*cos(x...
