**Course Description**

Pre-calculus weaves together previous study of algebra, geometry, and functions into a preparatory course for calculus. The course focuses on the mastery of critical skills and exposure to new skills necessary for success in subsequent math courses. Topics include trigonometric ratios and functions; inverse trigonometric functions; applications of trigonometry, including vectors and laws of cosine and sine; polar functions and notation; and arithmetic of complex numbers. Particular emphasis is placed on students' ability to reason critically on their own without the use of technology. The tests are broken into two parts: Part 1 covers problems that can be solved without technology and Part 2 covers problems that can be solved with technology.

**Course Goals**

Upon completion of this course, students will be prepared to move on to Calculus. Students will be able to apply trigonometry, vectors, polynomials and matrices to a variety of situations.

**Course Requirements**

Student taking this course are expected to have mastered the most important topics taught in an Algebra 2 course. Important topics to master are:

Factoring

Solving Linear/Quadratic Equations

Plotting points and graphs in the Cartesian Plane

**Target Audience**

This video course is primarily intended for students who have already mastered Algebra 2 concepts(typically 16+) and are planning on taking Calculus or for students in Precalculus or Calculus and need to review previously taught concepts (typically 17+).

**Technology**

The majority of the lessons are taught so that technology is not needed. However there are some where the use of a calculator or computer is required. Under the Additional Resources for Parents are tutorial videos that show how to use either online resources or a calculator to perform the work needed. The free online resources used are www.wolframalpha.com and www.desmos.com. The calculator used is the TI-83 which is the most commonly used graphing calcuculator in schools. If you use any TI calculator with the number 83 or 84, the instructions will be fine.

- 41 video lessons
- 41 skill worksheets
- 41 worksheet review videos
