Program Your TI84, Lesson 6: Solving Quadratic Equation

If you want to save time on your high school math homework using this TI-84 Calculator Program to find vertex of a quadratic equation. You have found the right article. The double slash "//" is a comment mark and that tells you what the calculator is doing in the program. These comments are not meant to be placed in the program.

Here is how this article works:

1. All BOLD type is what is meant to be typed into your calculator inside the program
2. // Introduce comments, these are not meant to be put into the calculator and are only there to explain what is going on.
3. // *** Program Start *** // & // *** Program End *** // Tell you when to start entering code and when to stop. The program name is included.
a. Try to use the same program names that way you can just copy my code without having to worry about changing all the names to work
4. The code will show up twice, once with the comments in them to show you how it works and again at the end without the comments so you can just copy the code into your calculator.
5. At the end of the Article you will find a tutorial guide on where to find certain calculator key strokes as well as other functions that I have created.
a. If I have created another function for another tutorial I will not retype it here, I will simply link to my other article and you can copy it from that one.
6. If you input a problem and it does not work out correctly please message me so I can update or change the code.
7. Just a note about naming conventions, I use my own naming conventions that make sense to me to keep things organized. It would be much easier if you used the same function names but it is not necessary.

// *** FQuadSol Start *** //
// FQuadSol accepts user input in the form of the coefficients of a quadratic formula
// Using the discriminant the calculator will then print out the solutions
// the quadratic equation will have as if it were completely solved.
// Most of the calculator out put will be on the graph screen where the pixels are smaller
// so more text can be fit, AxesOff turns of the x and y axes, the ClrDraw erases anything
// Left there from previous programs and ClrHome clears the regular calc screen
