Module 26 - Vectors Introduction | Lesson 1 | Lesson 2 | Lesson 3 | Self-Test Introduction Many quantities, such as speed, mass, length, and time, can be described completely by their magnitudes. However, both a magnitude and a direction are required to describe quantities like velocity, force, and displacement. To completely describe the velocity of a moving object, you need not only the object's speed, but also its direction. Quantities that are described by both magnitude and direction are called vectors. In this module you will manipulate vectors and use the TI-83 to visualize vector-valued functions and model projectile motion. Lesson Index: 26.1 - Vector Arithmetic 26.2 - Vector Functions 26.3 - Projectile Motion After completing this module, you should be able to do the following: Find scalar multiples of vectors Find dot products Graph and evaluate vector-valued functions in Parametric mode Model projectile motion on the TI-83 using vector-valued functions and Parametric equations Next > ©Copyright 2007 All rights reserved. | Trademarks | Privacy Policy | Link Policy
