# Ch 8: Parametric, Polar and Vector Functions

Brush up on your knowledge of working with polar forms, parametric equations, and vectors by watching these videos. Test your knowledge with the quizzes and exam in this chapter.

## Parametric, Polar and Vector Functions - Chapter Summary and Learning Objectives

This chapter wraps up in a nice bundle all of the graphing topics that don't fit nicely in all the talk of areas and lines. Start off with a discussion of polar coordinates, which represent three-dimensional objects, and how to convert between polar and rectangular form to solve parametric equations. Our instructors polish off this chapter with a brief discussion of vectors and how to solve missing variables in their direction or magnitude. Don't forget to take the quizzes and test to see how well you absorbed these lessons. The lessons in this chapter discuss:

• The polar coordinate system and shapes which are identified on it
• How to work with complex numbers in polar form
• Parametric equations and conversions
• Conic sections
• How to perform basic operations on vectors

Video Objective
Graphing Functions in Polar Coordinates: Process & Examples In this lesson our instructors describe how to construct and use a polar coordinate system to provide graphical depth, allowing one to evaluate shapes other than lines.
Complex Numbers in Polar Form: Process & Examples Learn how to convert complex numbers from rectangular form to find the power of a complex number.
Evaluating Parametric Equations: Process & Examples Here you will learn to work with single parameters in rectangular equations.
Converting Between Parametric & Rectangular Forms Instructors describe how to use the shape of a function in rectangular form to convert it into a parametric equation, and back again.
Graphs of Parametric Equations The focus of this lesson, besides the two-headed snake it uses for an example, is returning parametric equations to rectangular equations so they can be graphed.
Parametric Equations in Applied Contexts Watch this video to see how parametric equations can describe where an object is on a circuit at a given time.
Conic Sections in Polar & Parametric Forms In this video you will learn about so-called conic shapes, how they are defined, and how to represent them in standard, parametric and polar form.
Performing Operations on Vectors in the Plane Instructors explain how to add, subtract, and multiply vectors using the Cartesian plane in this video.
The Dot Product of Vectors: Definition & Application Get a quick lesson on how to multiply vectors to find missing angles or magnitudes in this lesson on dot products.
