WebSep 7, 2024 · The trick to get the real and imaginary parts in a complex expression is to substitute i with 0 to get the real part and then subtract the real part from the original expression to get the imaginary part. Use simplify for the surety. An example: WebThis is a Fourier sine transform. Thus the imaginary part vanishes only if the function has no sine components which happens if and only if the function is even. For an odd function, the Fourier transform is purely imaginary. For a general real function, the Fourier transform will have both real and imaginary parts. We can write f˜(k)=f˜c(k)+if˜
