Simply you can substitute theta=45 degrees (or any angle,not zero) in left hand side and right hand side.
or
using a^2 - b^2 =(a+b)(a-b)
= sin(2x+x)sin(2x-x)
= sin 3x sin x
For this problem the work would look like this:

Multiply -2 to both sides to isolate w.

Notice that the sign flips! This is because anytime a negative numbers transfers to the other side of the inequality the inequality flips directions.

Now this should be the solution once solving.
The attached picture below shows the graph.
Hope this helps!
