Hi all,
Can anyone please tell me how can I do the coding to complete this sum?
Also, how can I write down the code that adds up one term after one term and plots them? For example,
x = -pi:0,01:pi;
plot(x,term1); hold on;
plot(x,term1+term2); hold on;
plot(x,term1+term2+term3); hold on;
until all 7 terms! Thank you so much fro your help!!

Your sin(x) term is constant in n, so you can move it outside the summation.
x = -pi:0.01:pi;
sx = sin(x);
factor = cumsum(2./(1:7))
result = factor .* sx.';
plot(x, result)
