TRIGONOMETRIC RATIOS: Ratios of the lengths of the sides of a right triangle (related to the acute angles) The three most common ratios are . SINE, COSINE, & TANGENT. EXAMPLE 1 Find sin A, cos A, tan A, sin B, cos B, and tan B. Express each ratio as a fraction. EXAMPLE 2 Find sin S, cos S, tan S, sin E, cos E, and tan E.
