Version 2.2.2 is a minor improvement in program size and a major improvement in speed over version 2.1, and includes a couple of minor bug fixes left over from version 2.2. |

Not all features may be functional, and there may be bugs. There's still a lot of work to do before the v1 release, but i got the main functionality down, so give it a try and tell me what you think! A little knowledge about fractals and Juliasets is useful, but not required to use this program. Cheers! |

| **koch.zip** | 2k | 00-11-15 | | **Koch** The "koch" program draws on TI89's graph screen the fractal koch curve aka "snow blake" with a recursive function.

| **piecewise.zip** | 1k | 06-09-24 | | **Piecewise** This is an excellent program that graphs piecewise functions. It is capable of graphing between 2-6 functions, after which the user can zoom in/out on the graph and solve for a value. It also can find limits, which is especially valuable as the calculator itself cannot find limits of piecewise functions. Enjoy! |

| **piechart89.zip** | 9k | 03-04-25 | | **Pie Chart Creator** A simple program which creates pie charts based on the numbers you supply. I hope to also add labels for each of the slices to show percentages. |

| **polygraf.zip** | 4k | 03-10-19 | | **Polynomial Root Finder and Grapher** This update of Polygraf() changes the method of data input, making entry more user friendly and also making it easier to notice and correct errors. Roots are found much more quickly than in previous versions, especially for higher degree polynomials. Polygraf() finds all roots, real, complex, and repeated, of an nth degree polynomial equation, finds minima and maxima, and then graphs the polynomial function. The function can be displayed in fully factored form and allows you to toggle between Auto and Approx displays for the roots and factors. The program uses the cZeros() function repeatedly, and in many cases returns results in exact form rather than decimal form. Polygraf() is my alternative to the TI Polynomial Root Finder, which sometimes introduces small imaginary parts to real roots and vice versa, especially for repeated roots. For a more comprehensive program which includes Polygraf() as well as easy to use programs (none of the usual ()'s, {}'s, or x's to enter) for multiplying, dividing, and factoring polynomials, and for analyzing and graphing rational functions, see Polynom(). |

| **sierptri.zip** | 1k | 00-05-15 | | **Sierpinski's Triangle v1.0** Sierpinski's Triangle is the locus of points that is generated when starting with a point and randomly drawing another point halfway to the corner of an equilateral triangle, over and over again. This program generates it (it will look like triangles within triangles) and contains an explanation of a similar math voyage (using Pascal's Triangle). It also lets you save the picture in the middle, in case it has not yet generated the full triangle. |

| **slopefield.zip** | 6k | 04-05-09 | | **Slope Field** Slope Field is a somewhat useful program for students who are in calculus. It gives a visual representation of a slope field on your Ti-89 based on an input equation of the form dy/dx = f(x,y). I only used it about twice for homework, but it was fun to make and it even creates some really pretty designs with the right equations and window settings. |
