Summation Using For Loop
显示 更早的评论
I am having a hard time solving the following problem:
Here is what I have (for n=10) and I cannot for the life of me get the correct output, which should be 3.14 with a bunch of numbers after it.
clc,clear
format long
ESpi=0;
for k=0:10
ESpi=ESpi+[(-1)^k/(2*k+1)^3];
end
ESpi

Hi vaninea, Don't forget that you are calculating pi^3/32, not pi! Espi equals (appoximately) pi^3/32, so you need to work back from that in order to get to(approximately) pi.
