Prove the following identity. $cos_{4}x−sin_{4}x=cos2x$ We begin by factoring the left side of the equation. We can then use a Pythagorean Identity and a Double-Angle Formula to simplify $cos_{4}x−sin_{4}x =(cos_{2}x+=(cos_{2}x−sin_{2}x)=cos2x $

The given identity is

Then we have to prove the given identity.

First of all, we will write some im...
