#(2)/(1/tan x-tan x)#
1 Answer
I'm going to guess what you mean by simplify and say that this expression simplifies down to
Explanation:
(I am assuming that this problem is about rewriting a complicated trigonometric expression in different form; often this is done as an exercise of proving identities).
So we start with the expression
Using the identity that
Since
We can give this a common denominator.
Since dividing by a fraction is the same as multiplying by its reciprocal
Now if we remember the double angle formulas
