Module 23 - Parametric Equations Introduction | Lesson 1 | Lesson 2 | Lesson 3 | Self-Test Introduction Parametric equations can describe remarkably complicated abstract curves and they are also useful for describing practical real-world problems involving motion in two dimensions. In this module you will learn to graph and analyze parametric equations using the TI-89 and you will find slopes and arc lengths of parametric curves. Lesson Index: 23.1 - Parametric Graphs 23.2 - Chain Rule for Parametric Equations 23.3 - Arc Length of Parametric Curves After completing this module, you should be able to do the following: Define and graph parametric equations with your TI-89 Graph functions and their inverses in parametric mode Use the Chain Rule to find first- and second- derivatives for parametric equations Use the "Derivatives" feature of the TI-89 to find derivatives of parametric equations Use the "Tangent" feature of the TI-89 to find tangent lines and their slopes Find lengths of parametric curves using the definition of arc length Find arc lengths with the "Arc" feature of the TI-89 Graph Math menu Next > ©Copyright 2007 All rights reserved. | Trademarks | Privacy Policy | Link Policy
