Calculus: We consider telescoping series and their construction. Examples are (a) sum 1/(n^2 + n), (b) sum (2n+1)/(n^4+2n^3+n^2), and (c) sum (1/2)^{n+1}.

  • @zeedeveel421 A=1 and B= -1. The few lines below the statement show how we solve for A and B. Hope that helps. - Bob

  • Why do your partial fractions go from (A/n) + (B/n+1) to (1/n) - (1/n+1)? In other words, I'm wondering why you go from adding the two partial fractions to subtracting them?

  • @shawnvega Thanks for the comment.  Sorry about that. I'll see if I can fix it.

  • cool video, but some of the writing on the board is too small to read.
