1. Advanced Algebra Trigonometry
Introduction to Section 1.3– SOHCAHTOA
Objective: SWBAT to understand the underlying elements of Trigonometry ratios and to find indirect measures.

2. Trigonometry
Sine, Cosine, and Tangent are trigonometry functions used to solve for sides and angles of a right triangle.
You can only take the sine, cosine, and tangent of an acute angle.
The three basic trigonometric ratios are sine, cosine, and tangent, which are abbreviated as sin, cos, and tan, respectively.
