Sometimes changing my time origin allows me to find Fourier

Sometimes changing my time origin allows me to find Fourier coefficients more easily. Which of the following properties can change when I change my time origin?

A. The Fourier coefficients.
B. The symmetry of the wave function.
C. The RMS value of the function.
or D. The phase spectra of the function.

Solution

B) symmetry of the wave function
