PreCalculus

Introduction

This page contains resources that may be of interest to students studying Pre-Calculus. The number of resources on this page will grow as additional items are developed. If you have any questions or special requests, please contact Earl at earl@mathguy.us.

Handbooks

The Algebra Handbook covers numerous areas of study in Pre-Calculus.

• Algebra and PreCalculus Handbook version 2.9 – Covers two years of Algebra and one year of Pre-Calculus.
• Trigonometry Handbook version 2.1 – Covers High School Trigonometry.

Miscellaneous Topics

• Reflection Property of a Parabola – A 2-page description and proof that lines perpendicular to the directrix of a parabola reflect off the surface of the parabola and meet at its focus.

Sample Tests and Solutions

The value of reviewing these sample problems and solutions is twofold. The more obvious benefit relates to problems that a student has difficulty solving themselves; a solution is provided. Less obvious is the set of techniques used in our solutions; some of the techniques used on the sample problems may not be taught in the classroom. We concentrate on efficient solutions and shortcuts; so a review of the solved problems may present new techniques that enable a student to be more efficient in their approach to solving problems.
