The expression simplifies to a constant, a single circular function, or a power of a circular function.
Use fundamental identities to simplify the expression.
cot x tan x
Solution:-
First, write all of the function in terms of sines and cosines.
tan x = 
and cotx = 
.
This allows us to simplify the expression.
cot x tan x = 
= 1
Thus, cot x tan x = 1.
