How can i did the coding ?

Use Matlab software to draw a graph of the Fourier series approximations over square signal function, x(t), for k=1, k=5, k=25,k=50 and k=100. Use the equations in Fourier series and programming it using matlab script to plot these graphs. (Provide code and plot the graph in microsoft Word) . T= 2pi. Refer to the picture for the equation and graph.

At first you should try to define and plot your square-signal with plot() :)

If that works we can have a further look

From the image i assume you are trying to us the frac function to create the equation.

I suggest going through the following link for information on the fourier function and the functionalities it offers: https://www.mathworks.com/help/releases/R2019a/symbolic/fourier.html

The documentation help for frac function can be found on the following link:

Hope this helps!
