ANSWER
EXPLANATION
We want to simplify:

Recall the distributive property;
(a+b)(c+d)=a(c+d)+b(c+d)
We apply this property to get,

We expand to get,

This simplifies to,

The simplest form of the given expression is:

Answer:
see explanation
Step-by-step explanation:
Using the identity
tan x = 
Consider the left side

=
( multiply numerator and denominator by cos²x to clear fractions
=
← ( cos²x + sin²x = 1 ]
= cos²x - sin²x
= right side , thus proven
