Right sums for increasing N

Goal: We wish to display R_n for n=1, 2, 3, ....

The program:

PROGRAM: SUMS
:N+1N
:AX
:0S
:(B-A)/NH
:For(I,1,N)
:X+HX
:S+H*Y1S
:End
:Disp N,S

Step by step method for using the program:

• Choose Y= and fill in the formula for f(x) as Y1.
• On the home screen, store a in A, b in B, and 0 in S.
• Run the program. Each press of "ENTER" produces R_n for a new value of n.
