## Homework Statement

Hello everyone, I am currently experiencing a problem plotting harmonics in Excel.

I'm only able to plot the fundamental wave properly, I can't figure out how to plot the 3rd and 5th harmonic as they have a different frequency. Can you point me in the right direction, please...

## Homework Equations

vf=141.44sin(240*PI*t) - fundamental

v3=28.29sin(720*PI*t) - 3rd harmonic

v5=14.14sin(1200*PI*t - 1.2*180/PI) - 5th harmonic

## The Attempt at a Solution

Excel equation for vf

Degrees 0 to 360 (interval of 15) Column A2 to A26

=SIN(A2*PI()/180)*141.44

By using the above values I'm able to obtain a scatter plot but for the 3/T and 5/T the above does not work

I know that T=0.0083s not sure what else to add at the moment.
