just wondering if some1 can help me, ive almost understood but just need to finish things off.
1)I dont fully understand what the curly F is doing in the fourier transforms. Is it simply that
curly F of f(x) means f hat (x)? could some1 please shed some light on the function of the curly f.
2) why is it true that f(x) all hatted = f hat (k)?
3) i dont fully understand the sine and cosine transforms can someone please explain them to me.
