I've already set up the equation but i can't get this to work. What am I doing wrong?

Because you want odd harmonics only, you will need to change the n's within the sum to (2n-1):

You have the wrong type of summation operator. You need the one that looks like the summation in the first image, with placeholders top and bottom (you can get it with Ctrl Shft 4).

Hey Alan, thank you for your help, it looks great. One last question so would I have to change the value of N or little n? And is there a way to place the 3rd,5th,7th, etc. harmonic of the waves on the same graph or I can only do that separately?

For example,

y(4,t) = 3rd Harm.

y(6,t) = 5th Harm.

y(8,t) = 7th Harm.

Is that what I should put on the y-axis of plot?

Thank you,

Sha
