| **quadmsr83.zip** | 1k | 13-03-13 | | **Measures of a Quadrilateral v1.1** Given the vertices of a quadrilateral, this program will draw the shape and compute the lengths of the sides and the diagonals. I ported from a QBASIC program I saw in a Geometry Textbook in March 2003. I updated it 11 days shy of a full decade later to be more polite in restoring graphscreen settings and to add a missing file to the zip. Also supports the TI-84 Plus C Silver Edition. |

| **calcpi.zip** | 1k | 03-10-23 | | **CalcPi v1.0** This program uses Wallis' method to dynamically calculate pi. This is not a predetermined formula, like 4*tan^-1(1), but instead an infinite ratio that recalculates thousands of times, oscillating above and below pi and slowly narrowing in on the true value. The screen displays what the formula is, so you can see what it's doing. Have fun! |

| **circle112.zip** | 1k | 03-09-17 | | **CIRCLE 1.12** As you might be able to guess, unless you're clinicly insane or intelligence deprived, CIRCLE give you information about circles. Wow. It tells you the area and circumference of circles, gives you TSA and volume of spheres, cones and cylinders, and it has a really nice (but could be better) user interface. CIRCLE is pretty much the only program so far that I have written that has enough information to be totally self explanitory. |

| **slopfld83.zip** | 1k | 03-08-17 | | **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. This is a similar version of my 83+ Slopfld program. However, since the 83 does not support lower case letters and doesn't have as much memory, this version was necessary. |

It uses Archimedess theory of transposing a regular polygon inside a circle of radius one, and another polygon with the same number of sides outside the circle. Then increase the number of sides of the two
Pi should be somewhere between them. This program is neat to play with, but sadly it cant do any better than the Pi button on the keypad. |
