Define trigonometric ratios and solve problems involving right triangles. 6. Understand that by similarity, side ratios in right triangles are properties of the angles in the triangle, leading to definitions of trigonometric ratios for acute angles. 7. Explain and use the relationship between the sine and cosine of complementary angles. 8.

Example 1: Using the values shown in the diagram below, compute numerical values of these trigonometric ratios of the angle A. First write the ratio, then the quotient: sin A = = = cos A = = = tan A = = = Solution: Example 2: Compute the size of angle A in Exercise 1 using the inverse tangent function. Assume the lengths are exact.
