Solving Trigonomic Identities (4 Problems)

2 cot(x)=csc^2(x)*sin2(x)

csc(x)+cot(x)
---------------- = cot(x)csc(x)
tan(x)+sin(x)

tan^2(x)sin^2(x)=tan^2(x)+cos^2(x)-1

sin^6(x)+cos^6(x)=1-3sin^2(x)cos^2(x)

Solution Preview

csc^2(x)*sin(2x) =(cot^2(x)+1)*2sin(x)cos(x)=2cot(x)*(cos^2(x)+sin^(x))=2cot(x)

csc(x)+cot(x)
---------------- ...
