Hi guys, so I am having this problem with ploting graphics, I only need to do this simple Fourier Series and plot it, but it doesn't work. I will show the problems with some images and the program itself.

Before you try to plot a function, you should test the function for a couple of arguments

You function fails because of a division by zero for any argument you provide!

Reason is this:

The sum should start with i=1 and you have to deal separately with the signal's DC component if necessary.

You may also consider making n a second argument of the function f so you can compare the result of different number of summands

    Thanks for the observation, I understood the help note on the software. Think is the professors article was with this exactly expression. So I had no ideia how to solve it, added to it I am still studying this kind of Fourier Series and Solving circuits problems. Last but not least, how can I make the f(t,1), f(t,5) and f(t,100)? I am new at this software.Captura de tela 2023-07-18 221403.png

          Hello guys, this is Joao de Sousa Luz. First of all, thank you very much for trying help me out. Thing is I could reproduce Werner_E results, altough I still didn't tried to make diferente values such as f(t,1) f(t,5) and f(t,100), but the f(t,1) worked very well. I will try over to this week, but ttkoro answer I couldn't make it, at least your last answer. I will upload my test in mathcad.
