The first formula sheet document I am releasing for the TI-Nspire is one for trigonometry formulas. There are quite a few trig identities for students to memorize, so I hope this will serve as a good reference for you. This file will work for any up-to-date version of the TI-Nspire, including CAS or non-CAS, CX…

TI-Nspire Formula Documents
Over the next few weeks, I’m going to be releasing a series of TI-Nspire formula “cheat sheets.” Of course, cheat sheet is just a nickname for this kind of document, don’t actually use them to cheat. Having the formulas on your graphing calculator can serve as a very valuable study guide when you are either…
Math Nspired update includes Algebra II, Calculus
Texas Instruments today announced a significant update for their Math Nspired website. If you’re not familiar with Math Nspired, it’s a resource site for the TI-Nspire, primarily for math teachers, but to a lesser extent for students.
Video lesson: Tables on the TI-Nspire
The table feature allows you to quickly scroll the an x vs. y chart on your TI-Nspire. This lesson demonstrates how the table can be used from beginning algebra graphs to finding a limit in calculus.
Video lesson: Finding the intersection of two graphs on the TI-Nspire
In this video lesson, you’ll learn how to find the intersection of two graphs on the TI-Nspire graphing calculator.
Video lesson: Solving polynomial equations on the TI-Nspire
This video lesson explains how you can use the built in features features of a TI-Nspire to solve a polynomial equation, even ones bigger than a quadratic equation.
Video lesson: Definite integrals on the TI-Nspire
This video lesson covers how to find a definite integral on a TI-Nspire both within the home screen and within a graph.
Video lesson: Basic graphing features of the TI-Nspire
This video lesson covers and introduction to graphing on the TI-Nspire. Inputting equations, tracing functions, and adjusting the graph window, and using zoom features are all explained as well as find a maximum, minimum, or x-intercept.
Video lesson: Imaginary and complex numbers on the TI-Nspire
This video lesson includes a brief explanation of complex numbers and a tutorial on how to use your TI-Nspire to do calculations involving complex numbers.
Video lesson: Solving a system of equations with the TI-nspire
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…
