Texas Instruments: Calculus and the Ti 89

In this Computer Algebra System (CAS) activity, students will explore the concept of limits of functions, and use CAS to demonstrate the definition of derivative.

See examples of how to use the TI-89 in Pre-Calculus. Example topics include equations with radicals, trigonometric identities, composition of functions, and inverse functions.

This Computer Algebra System (CAS) activity encourages students to investigate the various functions and applications of the CAS calculator. They study and practice various types of problems in algebra and calculus with the help of the...

Learn how to graph a piecewise defined function on the TI-89 graphing calculator. Precise keystroke instructions and calculator screenprints are included in this lesson plan and student activity page.

Using a TI-Nspire calculator, learners will work to better understand function notation and input/output functions. They write equations with a function symbols, identify what makes an equation a function, and graph lines in order to...

Despite what most of us veiw as an excellent TI InterActive! Help file, my students have a difficult time getting the appropriate graphs after reading it. This is visual directions on how to enter piecewise functions in TI InterActive!...

Using the TI-89 calculator, students explore the statistical, graphical and symbolic capabilities of the TI-89.  Students investigate topics such as solving systems of equations, finding inverse functions, summations, parametrics...

Students determine the relationship between the stretch of a spring and the number of weights in a cup suspended from the spring. They find the Y-value of a function if the X-value is provided. They use technology to plot a set of...

Based off of the hit television show NUMB3RS, this lesson attempts to explain the betting system at horse tracks by having students vie for parcels of land on their calculators. Because the land boundaries are unknown until the finale of...

Read about the near-simultaneous discovery of Calculus by Liebniz and Newton, then see some examples worked through of finding derivatives of functions using the limit definition of derivative. Following the examples are exercises with...
