An all-in-one TI-84 Calculator Program designed specifically for the SAT Math section. This program will solve systems of two equations, quadratics, circles, lines, and much more automatically for you. This calculator program is the closest thing to a cheat code for the SAT. You won't need any other program. This is a math program for your TI-83 Plus calculator that solves a lot of formulas. Look for my new version coming later. The new version will have a lot more features. Mathtoolz.zip: 7k: 04-06-04: Math Toolz This is a little file I put together to help everyone with their math homework!

Distance Formula and Midpoint Calculator Program for TI-84. Easily program your calculator to solve the distance formula with our easy quick tutorial. Either download the program directly to your calculator (don't worry we'll walk you through it) or type the code in. HOW TO ENTER THE FORMULAS INTO YOUR CALCULATOR Imagine your Texas Instruments calculator buttons as a series of rows (across) and columns (up and down). This will help me point you toward the right buttons. The program 'PRGM' button is row 3, column 2: press that button first.

Memorizing the quadratic formula is a problem that can usually be solved with the help of a few helpful songs. But what many students fail to realize is that they can greatly speed up the rate by which they solve the problems.

Introducing The Quadratic Formula Program

One of the many secret weapons of calculator masters is now available for you to use!

You have two options here: You can either download a pre-written program to send to your calculator, or you can write the program directly on your calculator. Both will result in the same final result, it is up to you which you would like to use.

Option One: Download the Program and Send to your Calculator

Alright, let’s get started! Here is what you need:

A TI-84 Plus CE or TI-84 Plus C Silver Edition Calculator
Calculator charging cable
TI Connect CE Installed (Download Here)
Quadratic Formula Program (Download Here)

Grab your calculator charging cable, plug your calculator into your computer, and open TI Connect CE. Make sure your calculator is turned on!

Click on the “Calculator Explorer” tab on the sidebar.

You should now see a list of all the files on your calculator. Time to add another one!

Simply drag the Quadratic Formula Program you downloaded above into the list, and click the “SEND” button.

Option Two: Program it Manually on Your Calculator

Behold, the source code! If you are looking at this and have no idea how to put it on your calculator, here is a good video to help you out: https://youtu.be/z1jqegsr7dM.

Using the Program

Starting from your calculator home screen, press the [PRGM] button. Select the Quadratic Formula Program from the list, and press the [ENTER] button to run it.

The program will prompt you to enter the coefficients a, b, and c. After providing these to the program, it will display the solutions on the screen!

For example, if we have -X^2 +X+2, our coefficients are A=-1, B=1, and C=2. The X^2 coefficient is A, the X coefficient is B, and the final constant is C. If any of these terms are not present, just type in 0 as the coefficient.

If you would like your calculator to provide you with imaginary solutions, be sure to enter a+bi mode by pressing the [Mode] button and selecting a+bi mode.

Be sure to share this article with your classmates! I promise that they will love you for it.

Ever wanted to easily solve or factor quadratic equations without having to write out the formula and calculate manually? This detailed tutorial will show you how to program the quadratic formula into your TI-84 calculator so that all you need to do it type in the coefficient values! Start reading below for specific instructions, or press the button to jump directly to the complete code if you already know what you’re doing.

Creating a Program

To create a program, press the prgm button and scroll over to NEW.
You can name the program whatever you like, but its recommended that the name relate to the program’s function. That way you can easily recognize it and understand what it does from the title. I’ll name it “QUAD” here because it solves the quadratic formula. A helpful tip is to add an “A” to the front (“AQUAD” for example) so that the program is always near the top of your program list since they are sorted alphabetically.

Coding the Program

Begin with the program by clearing the home screen and adding inputs for the three coefficients.

: ClrHome : Input 'AX²: ',A : Input 'BX: ',B : Input 'C: ',C

ClrHome is found under prgm → > → 8
Input is found at prgm → > → 1

The colon is typed by pressing alpha → . and the space is typed with alpha → 0

So far, the programs clears the screen, then prompts the user for three values, which it saves to variables A, B, and C.

Next you need to calculate the values of x using the quadratic equation. We will save the two values to variables D and E.

: (-B+√(B²-4AC))/2A→D : (-B+√(B²-4AC))/2A→E

The “→” symbol, used to store values to a variable, is typed with the sto→ key.

Now that we have the x values calculated and stored, we just need to display them. To look nice, we’ll add a space between the inputs and results.

: Disp ' ' : Disp 'X=' : Output(5,4,D) : Disp 'X=' : Output(6,4,E)

The Disp command is found under prgm → > → 3 and is used to display something on the next line. The Output command, found at prgm → > → 6 is used to display something at a specific point. The first Disp creates a blank space on the 4th line, and the next two Disp commands display “X=” on lines 5 and 6. The two output commands display the numerical values of D and E at the 4th column of the 5th and 6th lines to match up with the “X=” strings.

Testing the Program

To test the program, exit out of the program editor by pressing 2nd → mode to access the main screen. Press prgm to access the program list and select your newly created program. Press enter to run it, and try figuring out the x-intercepts of the equation x² – 6x + 8 = 0. If the results are x = 2 and 4 then the program works! Keep in mind that the program will display an error message if there are no solutions or they are imaginary.
