QUESTION 3: It is a mathematical fact that any periodic function can be represented as an infinite sum of sinusoidal called the Fourier series. A periodic sawtooth waveform as shown in Figure 1 can be represented by the following Fourier series. f(x)= 2 (-1)*** sin(nx) TT n=1 n 1 th A' 0 -1 Figure 1 Create a plot that illustrates the construction of a sawtooth wave using the first 1, 3, 5 and 7 terms of the Fourier series for -31
