Consider the following sets of Fourier series coefficients.

Which of these sets of coefficients, if any, corresponds to f_1(t) = 2 - 2\cos\left({2\pi\over3}\,t\right)?

Now consider the following signal f_2(\cdot), which is periodic with period T=3:

Which of these sets of coefficients, if any, corresponds to this signal?
