Ti-83+ Integral Bug Fix

[evilgoodguy]

Thanks go out to Joe Doe for this bug report, I'm only in calc1 through a stupid miscalculation on the difficulty here, and so I haven't been able to use it. So without further adue, here's the easiest way you can fix it. And don't worry, even if you haven't done any coding, I will make it wasy:

1.) First you need to run the Integral program, make sure that it is unarchived. To do so, hit "PRGM" and go to Integral, if it has a star then it is archived, if not, then skip step 2.

2.) Ok, so to unarchive hit "2nd" then "+" then "2" then "1" then you should see a list of your programs. Find Integral, go to it and hit enter, the star should go away. If there is no star, you are good to go.

3.) Get into programs, "PRGM", now go to Integral and hit enter. You should see "prgmINTEGRAL" on the home screen. Hit enter again. And one more time. Now set these values:

f(x) = 1
g(x) = 1
A = 1
B = 1
N = 1
X-axis = 1
STOP!

4.) Do not set a value for "Y-axis" instead hit "ON" now hit "2". It will scan for a bit, be patient.

5.) Now hit "alpha" then down then "alpha" then down, then down two more times. You sould see something to the effect of:

":Output(3,7,fnInt(2(pi)X(Yo-T)-2(pi)X(Y9-T),X,A,B"

Change this line to:

":Output(3,7,fnInt(2(pi)(X-T)Yo-2(pi)(X-T)Y9,X,A,B"

6.) Now hit "2nd" then "MODE" and you are done. Now re-archive if it was archived. To do this repeat step 2 and make sure a star appears.
