Right Triangle Trig Evaluating Ratios Grade 9 Pdf Trigonometry Evaluating trigonometric functions means determining the values of sine, cosine, tangent, and their reciprocals for a given angle. there are multiple ways to evaluate trigonometric functions: using right triangles, the unit circle, trigonometric identities, or a calculator. This tutorial covers the reference triangle method for evaluating trigonometric functions at special angles.
Evaluating Trigonometric Functions Reference angles make it possible to evaluate trigonometric functions for angles outside the first quadrant. they can also be used to find (x, y) coordinates for those angles. The following figures give examples of the standard angle and the reference angle for the different quadrants. scroll down the page for more examples and solutions. Reference triangles are used to find trigonometric values for their standard position angles. they are of particular importance for standard position angles whose terminal sides reside in quadrants ii, iii and iv. remember that a reference triangle will contain the reference angle. As in the rst method, notice that any angle greater than 2 or less than 0 can be made into an equivalent angle by adding or subtracting 2 some number of times. at this point, we can use the formulas given above to reduce any given problem to that of evaluating sine or cosine at an acute angle.
