Step-by-step explanation:

I would use b.

Why?

I applied the identity sin(2x)=2sin(x)cos(x) in line 3 to 4.

OPTION B.

Step-by-step explanation:

It is important to remember these identities:

Knowing this, we can say that:

Now we need to use the following Double angle identity :

And solve for :

The next step is to make the substitution into and finally simplify:

b i think
