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.

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
