The table feature allows you to quickly scroll the an x vs. y chart on your TI-84. This can be useful as early as first year algebra for students that are just learning to graph. It’s even more helpful to calculus students using their calculator to help find a limit. The end of the video demonstrates a quick method for using the table’s “ask” feature to help find a limit.

In this video lesson, you’ll learn how to find the intersection of two graphs on the TI-Nspire graphing calculator. The two functions graphed here are a line and parabola, but you could use this same approach for the intersection of two lines, or virtually any functions the TI-Nspire can graph. It’s also certainly possible to have more than two functions graphed at a time. You just have to let the Nspire know which two functions you are trying to find the intersection of.
In this video lesson, you’ll learn how to find the intersection of two graphs on the TI-84+ graphing calculator. The two functions graphed here are a line and parabola, but you could use this same approach for the intersection of two lines, or virtually any functions the TI-84 can graph. It’s also certainly possible to have more than two functions graphed at a time. You just have to let the 84 know which two functions you are trying to find the intersection of.
When you are solving a quadratic equation, you have a lot of options. You can factor, complete the square, or use the quadratic formula. But what about polynomials with a degree (highest exponent) that is higher than two? These can be difficult to factor with the types of factoring you learn in a high school algebra class. This video lesson explains how you can use an app included with the TI-84+ Silver Edition to solve a polynomial equation.

This video lesson explains how you can use the built in features features of a TI-Nspire to solve a polynomial equation.
This video lesson covers and introduction to graphing on the TI-84+. Inputting equations, tracing functions, and adjusting the graph window, and using zoom features are all explained.
When you are given multiple equations and multiple variables, a graphing calculator can be a lifesaver. New versions of the TI-84+ come with a pre-installed app the makes these problems a snap. This video lesson covers solving systems equations by the elimination, or linear combination method, before covering how to use the TI-84 plus to solve. The lesson does require you to have the PLYSMT2 app installed on your TI-84.
When you are given multiple equations and multiple variables, a graphing calculator can be a lifesaver. Since the introduction of OS 2.0 on the TI-nspire, this is something you can do easily on your calculator. This video lesson review the “elimination” or “linear-combination” method before going on to explain how to solve these problems on your nspire. If you don’t yet have OS 2.0, you’ll need to get it for this lesson.
