Hi ShivamS
Sorry, missed that one. I don't see why it must be done numerically. You can just say cos(2 theta)=sqrt(7)/4 => sin(2 theta)=+/- 3/4.
Hi ganesh
I meant yours.
I went through your solution step by step and it seems to me that you lose the solution in the very last step.

Hi ganesh
There should be a Psi in there. It is the symbol for psychology.
It looks nicer for my eyes.
Hi Bob
I think a solution is lost in the third step, where you get rid of the outer cosine. The stuff on the left can also be -sin(theta)+2n.
Do you guys really not realize the I just cancelled the factor 5 in 65/70 to get 13/14?
It's not different. Look at the two more carefully.
Hi Bob
I tried doing the problem again. I am getting -3/4 only.
Hi bobbym
The problem is ill-defined.
Not without knowing 'width' too.
It does not do anything.
I found one solution using FindInstance:
I don't think that one can be solved analytically.
Should there also be a kaboobly doo button?
