Table of (indefinite) integrals. Contains over 200

formulae from standard forms to hyperbolic functions.





This is a grouped file for the TI-85 including the following:



* IntTable  - a program that displays the formulae (1087 bytes)

* IntTDat   - a list containing numerical data (353)

* IntTStr   - a string where all the formulae are stored (9041).



Uses variables B, C, I, K, N, P, X, Y, x (reals).

Requires about 11k, temporary variables included.



Transfer the uudecoded group file to your calculator via the link.

IntTable uses special characters which cannot be entered from the

calculator's keyboard. Hence there's no ascii listing included

(besides, you'd have very hard time typing over 10k of data!).



When run, IntTable displays a menu which shows all the usable keys:



F1...F5 - next to them are varying forms (e.g. choosing "au+b"

displays integrals involving au+b) so pressing F-keys displays

corresponding integrals



EXIT, MORE, < and > - EXIT quits the program, MORE displays the

next menu (or the first if you're looking at the last menu),

< displays the previous menu and > the next one.



Do note the following:

    * integration constant must be added (add +C after the form)

    * a, b, n, m, p, q... are constants, u and v are variables (or

    functions), just like x and y

    * the validity of a form is not included, you must know yourself

    if its ok to use it, say, 1/x can't be used if x=0 etc, and

    sometimes the constants are integers instead of real numbers...

    * often, 1/(x+y) (etc...) is displayed as (x+y)^-1, so consider

    it as denominator

    * the square of say, sin is sin^2 x for instance, but if a

    higher power is involved: [sin x]^n or [sin x]^(n+1) if

    sin x to the (n+1)th power

    * if there's "=" after the integral function, it means, of

    course, an alternative form

    * [1] integral... = ... means one form, after this there's

    [2] = ... a second form and so on (the forms are too long to be

    displayed all at once)



(anything else I should mention? :)



* I am not responsible for any errors or misinterpretations

(you can always perform derivation, to check errors)



* TO TEACHERS:

    This is NOT just another way of cheating! IntTable does NOT

    show any intergation methods and shows only the _final_

    result (in a test one must do it in steps). I created

    IntTable only to save time: I'm more into physics than math,

    and sometimes the integrals take considerable amount of time

    to perform -> the physics problem becomes a math problem :(

BTW: You're free to optimize, enhcance, modify the program, as long as

you distribute it with another name: making it a (possibly better) table of

formulae (math, phys...). Enjoy.
