New to mathcad. Expanding a function on mathcad

Good day. I want to ask how can I expand these example function to an infinite series of graph?

 

I already have a trial graph, but I want to learn how to expand it infinitely. My function keeps on getting errors on plotting. Hope you can help me.

 

Thank you in advance.

    Ramp is a mathematical function, It creates a repetitive ramp signal.

    It allows you to plot the function over an arbritary time period.

    But you could use one period of it to create the data for a Fourier series of the function. As such it should be able to replace ttokoro's function f(t).

      Attached you will find the worksheet for PRIME 7.

      The file consists of three sections: the first concerns the input of all the data, the second the programs (subroutines) for the development of a given function in Fourier series and finally the third which contains the functions and graphs.

        Thank you. I already have the solution using Fourier expansion, but I want to see yours too. Unfortunately, can I have a copy using mathcad prime 6.0? i can't open your file.

         

        I really appreciate this. Thank you for helping me out.
