Question 1203608: Use the fundamental identities to fully simplify the expression.
(-sin(-x)cos(x)sec(x)csc(x)tan(x))/cot(x) Answer by ikleyn(52797) (Show Source):
-sin(-x) = sin(x) is reciprocal to csc(x), so their product is 1.
cos(x) is reciprocal to sec(x), so their product is 1.
What is remained, is , which is tan^2(x). ANSWER
