Hi everyone,
My first time here, I have read about how to use this board, I wanted to give a Sigma sum, but cannot figure out how to do it. Please forgive me for the way I'm going to give the problem, hopefully in time I will get to understand the basics of this board. I have 2 Sigma related sums which I am sure fall within the category of Advanced Math...
Here is the first, please assist me with this, I am a father trying to teach my child who now is grade 12. I also help other students from time to time.
We have Sigma notation k=3 to n; (2k-1)n....we have to prove this is equal to n^3-4n. I evaluated the Sigma side and got to 2n^2+3n...whether I'm on the right track, I do not know, however, I do not know how to proceed with this. Could someone please assist me with this?
