How to Make a Quadratic Formula Program on a TI-84 Plus Image Credit: Shanestillz/iStock/GettyImages Graphic calculators provide an extremely useful function in modern mathematics courses and in a variety of real-world applications. The Texas Instruments series of TI-84 graphing calculators has been a core component of mathematics training for well over a decade. With these calculators, users can not only complete a series of complex mathematical visualizations but also create sophisticated mathematical programs that streamline a variety of otherwise complex mathematical functions. Advertisement Creating a quadratic formula calculator program on a TI-84 or TI-84 Plus calculator requires some time and effort, but it rewards the user with a valuable asset that will become a fundamental aspect of their studies for the future. Video of the Day ## TipCreating a quadratic formula program on a TI-84 Plus calculator requires a general understanding of the basic input functions of your device. Fortunately, the code for this program can be created relatively easily. ## Getting Started With Your Quadratic Formula TI-84 ProgramAs a first step, it is important to define the formula being used and the specific variables that will be needed to program it successfully. Although it is relatively easy to jump in and begin programming your TI-84 immediately, you will likely spend additional time and effort at a later point revising the work you have done if you don't complete this step. Advertisement The quadratic formula that will be used in your program is There are currently ## First Steps in ProgrammingAfter powering on your calculator, press the Advertisement If this is one of many programs you have created on your calculator or are planning on creating in the future, make sure that you ## Creating the VariablesNow that you have created the name of your program, you can begin initializing the variables that you will use. When the programming screen open, press the Advertisement At this point, you have successfully initialized the necessary variables. When you execute the program, the first thing you will see is a query for the numerical values associated with the variables in question. The next section of programming integrates these variables into the quadratic formula. ## Defining the FormulaAfter the variables have been created, the next step is to input the formula. Press the Advertisement On the next line of programmable code, insert the following formula: The nomenclature used here retrieves data stored in variables and uses them as part of the mathematical process. This is not the only line of formulaic code you need, however. Press Enter again and then input the next segment of the formula: Notice how the two distinctive formulas are being used to create a clearly defined X,Y pair. This information is particularly relevant given the applicability of the formula for graphing situations.

As a first step, input a set of open quotes. At this point, any content you type inside the quotes is displayed as part of the final result of the program. Advertisement For example, you can type, ## Testing Your ProgramPress the Advertisement After inputting this information, you should be able to press the ## More Programs to ExploreAfter completing your program, if you are interested in learning more about the various program options available to you with your calculator, a number of helpful online resources are available. In many cases, you are able to connect your phone to your computer and Advertisement ## Video |
