Which coefficients are zero in the following Fourier representation of f(t), where w=2pi/T? Explain. No calculation are necessary, but accurate and complete statements are required.
If you have a function f(t) as in your case in the some interval (-L, L) and determined outside of this interval by f(t+2L)=f(t). The fourier series or fourier expansion is given by your above formula.
The coefficients are give by:
The solution examines impulsive force of a large force that acts over a small time.
