How to Graph a Recursive Sequence on the TI-84 Plus

You can use the TI-84 Plus calculator to graph a recursive sequence and to graph the much more difficult Fibonacci sequence, one of the most famous sequences in mathematics. [more…]

How to Graph a Web Plot on the TI-84 Plus

Web plots are a really interesting representation of the behavior of a recursive sequence, and you can use the TI-84 Plus to graph web plots. Web plots actually look a little like spider webs. Following [more…]

How to Graph a Phase Plot on the TI-84 Plus

If you want to see how one sequence affects another sequence, you can graph a phase plot on your TI-84 Plus calculator to represent the data.

Enter two sequences that represent the population of rabbits [more…]

Graph Partial Sums of an Infinite Series on the TI-84 Plus

An infinite geometric series has a sum if–1 < r< 1. But, you can use the TI-84 Plus to graph partial sums. The partial sums should approach a number, which means the graph of a partial sum should have [more…]

Inserting Photo Images as Graph Backgrounds on the TI-84

An image is a digital picture that can serve as the background for your graph screen. Inserting an image on the TI-84 Plus is a great backdrop to practice transforming functions. [more…]

Quick Plot & Fit Equation on the TI-84 Plus

Images on a graph screen have another purpose that is now a built-in tool! You can use Quick Plot & Fit Equation on your TI-84 Plus to quickly plot points directly on your graph and perform a regression [more…]
