Introduction

Trigonometry is an unit included in the Geometry Pre-AP class curriculum at Clear Creek ISD. While some students are exposed to the very basic 3 terms, sine, cosine, and tangent prior to the class, most find the subject quite foreign. The purpose of this lesson is to introduce students to trogonomety by doing a web-search on the discipline at the beginning of the unit.

Learners
