Best ResponseYou've already chosen the best response.0on the side on sigma, it is sin\[\pi\] over 4

Best ResponseYou've already chosen the best response.0\[Ok so \sum_{n=0}^{3}\sin (n*\pi/4)\] So like this?

Best ResponseYou've already chosen the best response.0The sigma represents a summation. So if it were \[\sum_{n=0}^{3}n\] we start with n=0 plug that value in and keep adding until we reach the limit which is the top value on the sigma, 3.

Best ResponseYou've already chosen the best response.0So we'd have 0+1+2+3 and then stop.

Best ResponseYou've already chosen the best response.0so when n=0, the whole thing would equal 0 right?

Best ResponseYou've already chosen the best response.0Yes. You start with whatever n equals under the sigma and plug it into the function to the left of the sigma and then go to the next sequential n value and add it to that result.

Best ResponseYou've already chosen the best response.0so do i just start with n=0 and I get 0, then n=1 I plug it into n*pi over 4 and that equals .785 and so I add that to the zero.... then i go on to n=2 and keep adding on to the .785......
