Hello,
You want to go from exponentials to sines.
So you should remember this formula :
but here, you have things like
so try to see what happens if you multiply the sine formula by , to get 1 on the right side :
and finally,
which is equivalent to (t=2x)
Applying this to the formula you have :
note that 2i can be simplified :
now using simple property of exponents, we have
and this finishes the problem :P
