Hello, I am am trying to plot the equation "sum" but im not sure what to do with the undefined variable t
clear, clc
for k = 0:9
n = (2*k + 1);
sum = (4/(pi*n))*sin(n*t)
end
plot(sum)

What is t.
Is it suppose to be time? For what period? Do you know what you are trying to plot? Are you trying to create multiple plots in the same figure, using time as an independant variable (my hypothesis)? Do you have two independant variables with k also being one?
We need the full story to be able to help you

Also, try not to name your local variables after built-in functions with the same name. Rename your sum variable to total instead.

Make a random vector for t make sure it has 10 elements in order to plot sum vs t
use for example t= 0:1:9
or maybe use linespace
