Question 291874: Verify identity
cos(theta) cot(theta)=1/sin(theta)-sin(theta)

cos(theta) cot(theta)=1/sin(theta)-sin(theta)


cos(theta) [cos(theta)/sin(theta)]=1/sin(theta)-sin(theta)

cos^2(theta)/sin(theta)=1/sin(theta)-sin(theta)

[1-sin^2(theta)]/sin(theta)=1/sin(theta)-sin(theta)


1/sin(theta)-sin^2(theta)/sin(theta)=1/sin(theta)-sin(theta)


1/sin(theta)-sin(theta)=1/sin(theta)-sin(theta)
