 TI84 Plus CE Programs

 TI84 Plus CE BASIC Math Programs
These files are for the TI84 Plus CE, 83 Premium CE, and other "CE" calculators with color screens. BASIC programs are compatible with the TI84 Plus CSE and some BASIC programs written for monochrome 83+/84+ calculators will also work correctly. Assembly and C programs must be written for the CE calculators specifically; running them on calculators with an OS newer than 5.5 requires jailbreaking the calculator.

This is a TIBasic Program that does Math for you, It has Geometric Figure, Slope, Inequality, Equations, Calculation, and even graphing. It is also available for TI 84 Plus C Silver Edition! You can download here or on the TI 84 Plus C Silver Edition Archives, it doesn't matter. If you liked the program, please consider rating it, because it encourages me to bring more and more features to this program. This is the version RELEASED 1.0.1 –– Critical Bug Fixed, 26 AUG 2018, please constantly checking for updates

Calc2 is (in my opinion) a program that makes calculations MUCH easier. With auto fractions, equation solving, and more, it is a pretty awesome program. It is based of the builtin calculator in Mathtools, also made by me.

Graph3D v4.1 is a rewritten version of my decadeold TIBASIC 3D graphing application for the TI84 Plus C Silver Edition, taking full advantage of the new colorful LCD. It is a fullyintegrated 3D graphing utility that can graph up to 6 simultaneous 3D equations of the form Z=f(X,Y). You can edit the window settings, zoom settings, and format from within the program. You can trace over any graph, and rotate and zoom graphs from the graphscreen. Among many other tweaks, this version overhauls the rotation code to be faster and more accurate compared with its monochrome ancestor.

This is a port and upgrade of Trig Finder v2.0 to the TI84 Plus C Silver Edition. It now supports all possible angles, both degree and radian measures, and will automatically fix your angle settings when it quits. Simply run the program, enter the angle in degrees, and the program will give you all six trig functions for the angle: sine, cosine, tangent, secant, cosecant, and cotangent. Also includes a Doors CSE 8 icon.

angles of a right triangle. With an easy to use interface and extremely quick solving, it is a must have for people taking
units related to right triangles. This is one of the many tools that will soon be available in Mathtools: Geometry Edition. 
This program calculates the mean, median, range, and standard deviation of a list of numbers. It also includes a line grapher that will plot your points and draw a line of best fit through them. Enjoy!

This is version 2.0.4 of the TIFC. The previous version only supported roughly 68 conversions, took 4 programs and a picture variable, and was around 6kb in size. Version 2.0.X supports the usage of a single program, and boasts 708 conversions available in this single program of just over 7kb in size. It is also available for the TI73, TI82, TI83, TI83+/84+ and TI84+CSE, with the potential of being programmed on other calculators at a later date.

This is a constant work in progress. Slow, but still making headway. Requirements:  TI84+ CSE  Does NOT require Doors CSE8 (future support possible) Changelog: v2.0 beta 3  Totally revamped and included my Triangles program (TRIANGLE)  Totally revamped and included my Pythagorean program (PYTHAG)

The program ARC84C calculates the arc length of function Y1 between any two points. The function is then plotted and the arc length is colored in red. You can use the function Y1 in storage or enter a new one.

This calculates the area between two curves, Y1 and Y2. This

program works best if you can set the graph screen to where the
curves intersect at only two points. The program first searches for
two intersections, one from the left side of the graph screen (Xmin)
and one from the right (Xmax). After the area is calculated, both
curves are graphed and the area between curves are shaded.
Function and Radian modes are used. 
This will sketch any angle, in radians or degrees. Read the included readme for further directions/information.

Unlike other Quadratic Solvers, this will automatically simplify the equation to it's best ability. No decimals! (v1.1  No longer displays an unnecessary "1")

This base converter is very simple to use. Converts bases from 232 and works very well! If you get errors, try deleting all variables and strings and try again. Message me if you have any problems.

This small and nifty math program takes two polynomials of any size in the form (A*X^B*Y^C...)(A*X^B*Y^C...). It then expands these two polynomials and combines like terms. Save time, reduce error. Note: This program requires the newest version of the TI84 Plus CE OS, because of the toString command used in displaying results.

If you have any problem with your graph or if a program left something there this programs is for you. This program resets your graph to its default's and fixes any problems on the graph. Not any problems with Y1Y9 those can be erased by pressing the Y= button. Thanks for downloading if there are any problem please feel free to message me.

This program was initially created in November 2016 by Kaleb Allinson (My AP Calculus teacher), but i looked at the code and said that i could make it more user friendly to normal (noncalculator savvy) folk, so he let me. This program is for using Newton’s method of finding the xintercept(s) of a function in Calculus. THis program will work on the TI84+(SE), TI84+CSE, and TI84+CE calculators. Enjoy!! :D 
F15 is a fractal grapher with many features: plot Mandelbrot, Julia, Sierpinski, and custom formulas; customize color preferences; adjust pixilation range from 7x7 pixels to 1x1 pixel; customize iteration range; and do much more. The mystery of fractals is now easily accessible to everyone.

Enter a polynomial. Same syntax as PEMS. However, this has one crucial change. One that took weeks of working on the engine...
MULTIPLE VARIABLES!!!
While PEMS has support for expressions like *:(x^2+x)(x+45)
ExpandCE can expand expressions such as *:(x^2+5y^2x^5z^2)(99B^2*54x^3)
Warning: This is an early release. There will be bugs. If you see one, please PM me.
Note: This is SSSSLLLLOOOOWWWWW. The engine has a lot more work to do. While I'm working on speeding it up, if you don't need multiple variables don't use it.

This Pi Day 2013 tribute program for the TI84 Plus C Silver Edition teaches trigonometry while you eat pie. You choose the amount of pie to eat, first an amount, then whether that's times pi or not, and finally if the angle is degrees or radians. Along the way, the program will show you the sine, cosine, and tangent, of the angle of pie you have eaten so far. A fun way to visualize angles and trigonometry.

By using the arrow keys you can change the degree measure and then hit ENTER to see the Radian measure,
the sine (y/r), cosine (x/r), tangent (y/x), cosecant (r/y), secant (r/x), and cotangent (x/y) values of the selected
degree measure.
