Hi all, how would I plot every iteration of the sum? It's and approximation of cos, getting closer each iteration. Thank you in advance!
x = -pi:0.1:pi
sum = 0;
n=(1:1:5);
for k = 0:n
kTerm = ((-1).^(k)).*((x.^(2.*k)))./(factorial(2.*k));
sum = sum + kTerm;
end
sum
hold on; grid on
plot (x, sum, ':b')
plot (x, ye, '-r');
