QUESTION 3: A periodic saw-tooth waveform as shown in Figure 1 can be represented by the following Fourier series. y M)=?r(-1) -1 n 2 sin(x)=sin(x)---sir T -sin(2x)+... 141. 2TT ... X Figure 1 Create a plot that illustrates the construction of a sawtooth wave using the first 2, 3, and 4 terms of the Fourier series for 0 ≤ x ≤ 6n (i.e., your plot should have 3 curves that become successively better approximations of the sawtooth wave). Label all the axes, include gridlines and a legend in your plot. Change the axis limits so that the x-axis ranges from 0 to 67 and the y-axis ranges from -2 to +2, and change the line width to 1.5 for all three curves. X Hint: type "help plot" in the Command Window, scroll down and see the example for changing line width.
