Can you show the work for these, Use the trigonometric identities to solve each equation within the given domain.
1) -sin2(x)=cos(2x) from [-PI, PI]
2) 3tan(x)=2sin(2x) from [0,2PI)
3) sec(x)cos(3x)=0 from [-Pi/2,PI/2]
4. 1-cos(x)=2-2sin^2(x) from (-PI, PI)
5. 4cos4(x)-5cos2(x)+1=0 from [0,2PI]

As well as: using the trigonometric identities to verify each expression is equal

1. csc2(x)-2csc(x)cot(x)+cot2(x)=tan2( x/2)
2. [cos(x)cos(y)][tan(x)+tan(y)] sin(x+)
