I'm not sure about you, but my calculus teacher told me there was no way for my calculator to calculate the area between curves at the touch of a button. Well, these TI89's are off the chain but I've come up a with a nice little patch that lets our little beaut's perform just the same. ** Entering equations If both Y1 and Y2 are populated, curves will choose those two equations and find the area between them. If one or more are blank, you will be prompted for both. *** Change your mind? Press `Y=' during calculations to change the equations, or `TRACE' (window) to change the domain in which intersections are calculated. ** Caveats I wasn't in class long enough to make this program sophisticated enough to comprehend vertical bounds, or know how to react if only one equation was within range of the window. This program will function just fine if you can see everything of interest on the graph, so just use those settings and let this do its magic. ** Output After calculation, the totaled area will be shaded, the final answer stored to Ans, and a message will be printed on the screen. |

If you input: A^X, the program gives, ln(A)*A^X. If you input: sin(X) ( Don't forget the right hand bracket! ), the program will give, cos(X).

| **newtonsapprox.zip** | 1k | 09-12-02 | | **Newton's Method of Approximation** Whilst sitting in calculus class, I got bored. Naturally I made a program to simplify what we were learning and share it with the class. So here it is, Jorgan Pubshire's official Newton's Method program. This is the best Newton's Method program because not only does it approximate your zero, it also builds your entire information table through what I call a cascading table display. Also, this program can do an infinite number of iterations. There are two modes in this program: Iteration mode allows you to input a set number of iterations to be ran and Accuracy mode runs iterations until it reaches an accuracy that is set by the user. My teacher had already made this program a couple years ago and when I gave him my program he admitted that mine was better. There literally is no way to make this program better save converting it into a fancy flash program, but since I can't do that yet, this will have to do. Enjoy! |

Func Master is special because it is fairly small when compared to other calculus programs that perform similar tasks. It also does not require you to install supporting applications like Symbolic or Pretty Print, so it will be ready to run as soon as you put it on your calculator! This program is highly recommended for general use and for AP Exam free response questions. Read "help.txt" below for more information. Also note that ticalc.org may not have yet updated the screenshots for this program. |

| **recursiv.zip** | 1k | 07-03-06 | | **Recursive** prgmRECURSIV represents numerically and graphically recursively-defined sequences. 1,2,3...n is stored to L1, while A[sub](k+1) as a function of A[sub]k is stored to L2. The sequence is plotted against its term number (in a graph situation), though reading off L2 for the sequence is more handy (especially for busy-work). The graphs are interesting, however; the graph of A[sub](k+1)=3A[sub]k, for example, increases like a geometric sequence with a common ratio r=3. |

| **sequence.zip** | 1k | 07-03-06 | | **Sequence** SEQUENCE is designed to numerically and graphically represent the sequences that result from all types of functions, especially those whose values only carry meaning in the domain of the natural numbers: factorials, series, alternating series, etc. f(n) is evaluated for 1,2,3...n (the domain automatically stored to L1); stored, and displayed as L2. ZoomStat displays the (L1,L2) alongside Y1. |

(2) Flexible (e.g., settings for the window variables and slope-field lattice are user-specified and independent of each other). (3) Easy data entry and navigation (e.g., cancellation reminders are on data-entry screens). |

In the screenshots, it does not show the center, but it will be there when you run the program. |

| **slopfld.zip** | 1k | 06-09-08 | | **Slope Field** This program calculates a slope field for a given derivative. The slopes can be defined in terms of both y and x. There are also many menus that allow you to customize your slope field. You can set the window and the amount of resolution. It eats up a ton of memory while you're running it, so you may need to either archive things, or set the resolution to "low". This updated version fixes a minor bug and causes the program to run much faster than before. It also provides an opportunity to input a solution to the differential equation and view its graph on the slope field. |

| **newton.zip** | 1k | 06-09-08 | | **Newton's Method** This program uses Newton's Method to find roots of a given function. After inputing an initial guess and error, it finds a sequence of estimates and stops when the difference between estimates is less than the given error. |

| **euler.zip** | 1k | 06-09-08 | | **Euler's Method** This program uses Euler's method to solve a differential equation. For a given diff eq, and initial point, you determine the number of steps you wish to take in order to approximate the y-value for a chosen x-value.

| **gamma.zip** | 1k | 06-08-13 | | **Gamma Function solver** This program solves Gamma(n), which is (n-1)! for any integer value or for non-integer values it is the integral of something nasty from 0 to infinity. Most efficient algorithm you will find anywhere. |

| **newtonjm.zip** | 1k | 06-07-17 | | **Newton** It may seem like another Newton iteration program, but I've written this one to have a few special touches to it that make it worthwhile. First, the program displays the equation (Y1) upon loading. After asking for an X value to be the starting point, the calculator tests that value. If the derivative of Y1 at that value returns an answer of zero (thus making Newton's method [x - f(x)/f'(x)] divide by zero), the calculator will display "Pathological Error: d/dx = 0." If that X value does not immediately return a derivative of zero, after 50 unsuccessful iterations the calculator will assume that there is a pathological error, and will display the same error message as before. I added the pathological error aspects to this program because the typical Newton iteration program will continuously attempt iterations before the "divide by zero" error is displayed (if it ever is), wasting both time and batteries. |

| **calcbc.zip** | 4k | 06-05-26 | | **Calculus!** Features ten different programs, including slope fields, average value, Riemann Sums, line analysis, and triangle analysis. As a bonus, all of this is integrated into a nice GUI. |

| **advderiv.zip** | 8k | 06-05-18 | | **Advanced Derivative Function** It will calculate F'(A) based on the nDeriv( function. However, it will first check if the function exists in A. Then it will use the nDeriv function but with a better precision. If the derivative is very high, it will warn you that it could actually be +/- infinity. So in general the solution is more reliable than the normal nDeriv function. |

| **simpsonrule.zip** | 1k | 02-03-21 | | **Simpson's Rule** Allows you to input the beginning and end of the interval ("a" for the start, "b" for the end) and the number of subdivisions ("n").
