Students will review:
This chapter helps students review the concepts in a polar coordinates and parameterizations unit of a standard high school precalculus course. Topics covered include:
- Graphing functions in polar coordinates
- Complex numbers in polar form
- Evaluating parametric equations
- Converting between rectangular and parametric forms
- Conic sections in parametric and polar forms
1. Graphing Functions in Polar Coordinates: Process & Examples
After watching this video lesson, you will be able to convert any Cartesian coordinate point into a polar coordinate point. You will also learn how to plot these points.
2. Complex Numbers in Polar Form: Process & Examples
After watching this video lesson, you will be able to convert complex numbers from rectangular form to polar form easily by following the formulas you will see here. You will also learn how to find the power of a complex number.
3. Evaluating Parametric Equations: Process & Examples
After watching this video lesson, you will be able to evaluate a parametric equation for any given parameter. Learn the steps involved and what the complete answer looks like.
4. Converting Between Parametric & Rectangular Forms
There are all kinds of ways of writing equations. Learn about parametric equations in this video lesson. Learn how you can convert between parametric equations and their equivalent rectangular equations.
5. Graphs of Parametric Equations
Watch this video lesson to learn how you can go about graphing parametric equations. Learn the simplest way to graph parametric equations by eliminating the parameter.
6. Parametric Equations in Applied Contexts
Watch this video lesson to learn how you can use parametric equations to help you solve real world problems such as the path of a moving object. Learn how to form parametric equations to model the real world.
7. Conic Sections in Polar & Parametric Forms
After watching this video lesson, you will learn to distinguish between the standard form equations for conic sections, the parametric form equations and the polar form equations.
8. Parametrics: Definition & Equations
Parametrics are a special type of mathematical expression that build on traditional rectangular equations. Learn how parametric equations can be used to simplify problems, create graphs, and enhance our understanding of the behavior of those graphs.
