Ever wish that you could have a program on your calculator to do long drawn out formulas for you? With this tutorial you will be able to program formulas into your calculator with ease.
This is for anyone who wants an easier human-error proof way to derive the answer to several formulas. It is especially handy for those among us who are engineers and don’t want to do computation by hand.
You can program any formula that uses inputs into your calculator using this process. You can program formulas such as the formulas for Reynold’s Number, the Quadratic Formula, Antoine’s Equation, the volume of a sphere, Pythagorean Theorem; the possibilities are endless. For demonstration purposes I will be using the coding for the quadratic formula.
**At the bottom of the instructions I have an "If you messed up really badly" section that should be noted here just in case you find yourself in a dark abyss with your program and don't know where else to turn.**
What You Will Need
-A TI-83 or TI-84 plus calculator (these instructions may work for other calculators as well)
-A copy of your specific formula
-A previously calculated answer for your formula so that you can test out your program to see if it is working correctly
