Welcome to the PF.
Your attachment is sideways and pretty hard to read. Can you please type your work into the forum? That makes it a lot easier to respond.
There are math symbols in the Edit bar above the edit window under the √ symbol, and there is a tutorial about how to use LaTeX under the Help pages (see INFO at the top of the page). Thanks.

Hello Ahmad, 
!
My neck still hurts from trying to read your picture ( I use a desktop, not a phone). For the sake of others I re-post it:
I notice your x is not the ##x## in the exercise (which is your ##\theta### ) so that deciphering isn't just painful, but also confusing.
As @berkeman (who types faster
) says: could you re-post and explain what it is you write down?
In the mean time you can try to find a relevant equation that links ##\cos\theta## and ##\cos(\theta/2)## and post that too
Oh, and: read this
