Verify the identity csc(x)/cot(x)-cot(x)/(1+csc(x))=tan(x). Working on the left hand side (LHS), the two terms are combined by first writing them over a common denominator. The numerator is simplified using the Pythagorean identity 1+cot^2(x) =csc^2(x). The fraction is simplified. and finally the remaining term is written in terms of the tangent function.
