So we know the following:
-------------------------------------------------------
Which will be used below
Replace with (since )
Replace with (since )
Replace with (since )
Replace with (since )
So in the end, simplifies to
In other words, is an identity (true for all real numbers )
Let me know if you need more help or if you need me to explain a step in more detail.
