If I have a problem like
(N) sigma (K=0) Cos(Kpi)
can I just move the sigma sign inside the brackets? like
Cos(pi Sigma K)
just wondering because I have this on an assignment problem and we didn't learn it in class and the textbook doesn't cover it either. If I can move it inside the answer is easy so I am just assuming that's how to do it.
Also, how do you guys write all the math symbols, etc. I see them in other posts but I am pretty much useless on a computer so I have no idea how to do it.
Thanks
