You can put that equation in the “y = “ thing then go back to Home Screen and in a fraction, type (y1(12)-y2(10))/(12-10), giving you the answer of -88
Hey! Does anyone know how I can "unstore" (sto command) the letters... meaning how do I revert it back to letters A,B,C.. etc. Just wondering if there is an easier way rather then resetting the ram on the calculator. :)
This video is a misleading trap into leading desperate students into a way to cheat through their exams. Your procedures, which surely only work on your specific Ti-xx, are also completely useless. Uses of the calculator are and have been known for years, per their documentation. Stop this misinformation of there being some sort of shortcut to making algebraic calculus work in this calculator; it can’t be done when tests are based off of exact algebraic values. Shame on you.
The TI-84 is one of the most common graphing calculators that people use I don't get why you act like this is some niche calculator that no one uses. And I also don't get what you are saying I've been studying calculus for a few years now and a calculator has always been useful tool for me and I'm sure for countless other people too. Just because an exam uses exact algebraic values doesn't mean a calculator can't be useful. You have no idea what you are talking about.
