Fourier Transform of f(x) = cos(3x-2)

73 Views Asked by At

I was thinking of using the same approach as is stated here but I believe that wont work due to the 3x-2. I'm trying to use the trigonometric identity for sin(A-B) = sin(A)cos(B) - cos(A)sin(B), but I somehow am confusing myself in the middle. Any thoughts or hints would be greatly appreciated
