# Algebra Trigonometry - Polynomial and Rational Functions

### Requirements

- You need to have a computer connected to the Internet to watch the lectures.
- Ideally, you need to have taken the course prior to this: Algebra and Trigonometry - Linear Functions which can be found on Udemy.

This course teaches you **all the important underlying concepts in Polynomial and Rational functions** in mathematics. The knowledge that you gain here can be further completed in our next courses towards a complete mastery of calculus.

This course covers the following topics:

- Quadratic Functions
- Power Functions and Polynomial Functions
- Graphs of Polynomial Functions
- Dividing Polynomials
- Zeros of Polynomial Functions
- Rational Functions
- Inverse and Radical Functions
- Modeling Using Variation

This course has been taken from chapter 5 of the book, **"Algebra Trigonometry" from openstax, ISBN-10: 1-947172-10-7**. The book can be downloaded free of cost from their website. All chapters of the book have been planned to be produced as a video course by us. This course contains around **175 videos each averaging 15 minutes**. Using this course, you'll learn polynomial and rational functions from scratch really well.

Also, this course can be taken as part of a series that will take you all the way up to **mastering calculus**. All the courses in the series will be taken from the same book described above and other calculus books from openstax. You can read our** "Mathematics" page on "GreatITCourses" website** to make yourself **more familiar with our road map**. A Google search will take you to our website.

- Anyone who wants to learn polynomial and rational functions.
