Fourier transform of hat function

1. The problem statement, all variables and given/known data
obtaining the fourier transform of the hat function
h(x) = 1 if modulus of x</= 1
=0 otherwise

2. Relevant equations
F(k)=1/sqrt(2*PI) *integral from -1 to 1 of exp(ikx)

3. The attempt at a solution
I've carried through the transform and got an answer of
could someone tell me if this is correct please?
