## Plotting Parametric Equations on the TI-83+ and TI-84+

We at Calcblog hope you had a great winter vacation! So far, we’ve posted tutorials on graphing in rectangular/Cartesian and polar coordinates, but there are other ways to specify functions. One of these is as a function of a parameter, …

## Sums and Sequences on the TI-83 Plus and TI-84 Plus

While they may not have the calculus capabilities of the TI-89, the TI-83 Plus and TI-84 Plus have two great functions for dealing with series and sums, the “seq” and “sum” functions. This tutorial explains how to use these features …

## Riemann Sum Program for the TI-83+ and TI-84+

RIEMANN, a program for the TI-83+ and TI-84+, approximates the area under a curve (integral) by calculating a Riemann sum, a sum of areas of simple geometric figures intersecting the curve. The program solves Riemann sums using one of four …
