a) List all symmetries applicable to the periodic function shown above. b) Find the Fourier series coefficients av, an, and bn for f(t); must show all work for full credit. c) Using the formula for the rms value of a periodic function, show that 1 n2 =1 = 2 6 [Hint: first find the rms value directly in the time domain (easy), then make use of the frequency domain formula.]
