AREABTWN.zip  Area Between Curves (TI84 Plus C Silver Edition) [] 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. 

BASE.zip  Base Converter [] 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.

ExpandCE.zip  ExpandCE [] 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.

INTRPOL8.zip  INTRPOL8 If you have a function you can use the CALC menu to find a value, find a zero of the function or find a maximum or a minimum. What if you only have equally spaced data points available without any functions? It is still possible to use only that data to obtain a value, find a zero of the function or find a maximum or a minimum. The process of doing this is referred to as “Interpolation”. In general, the data can be in the form of a table, however, it is not required that the data come from a book. It can also have been generated by your calculator or a computer programmed with a set of equations to complex to be entered into your calculator. You can even obtain the data points from an experiment in a laboratory. INTRPOL8 will find all of these and it can do more. It can find the number that is exactly halfway in a set of numbers and it can generate a difference table of your data (up to 5 points). It also can create a function that will reproduce the data you supplied and it can plot out the data. And it does all of this usually using only 3 or 5 data points.
