You can plot for various values of t between 0 and 1.

t=.3%not sure what you want to plot against, I held t constant and plotted N vs. error

n=1:2:100000;%have to pick something for infinity (100,000 should be good for about 5 decimal places)

N=1:2:500;%whatever you want N to go up to

x=(4/pi)*sum((1./n).*sin(n*pi*t));

e=arrayfun(@(y)x-(4/pi)*sum((1./(1:2:y)).*sin((1:2:y)*pi*t)),N);

plot(N,e);
