Partial Sums of a Recursive Series (basic)

Name:         Psum: psumrecg, psumrect
Author:       Wilson W. Ng   Waesh@yahoo.com
Version:      1.0
Machine:      TI-82, TI-83, and TI-83plus
Released:     May 8, 2002
Description:  Sequence and graph of partial sums. Table and graph option included.

------------
Instructions
------------
Psumrecg and psumrect are subroutines. Run Psum as the main program and hit
enter at title screen.

For the 82, go to the graph menu and enter your equation

(Y1) enter your equation
(L) initial n-value
(A) initial term
(M) number of terms


Example:
	1/2+1/4+1/8+1/16...defined recursively as sigma An, where An = (1/2)A(n-1), A1 = 1/2

Enter (1/2)A for (Y1)

1 for (L)

1/2 for (A)

20 for (M)

Then select graph or table.


--------------
Known Problems
--------------
There might be some minor problems with the program. This version was ported 
from my 86/85 without testing the program on the 82, 83, and 83 plus. However,
I looked through the texas instrument guidebooks in the programming section of
the 82 and 83plus. If you know a little about basic programming, you can probably
fix the I/O and Ctrl errors.
