To answer questions such as this one, we need to evaluate the sine or cosine functions at angles that are greater than 90 degrees or at a negative angle. reference angles make it possible to evaluate trigonometric functions for angles outside the first quadrant.

If you are in this course, then you should already by fairly familiar with trigonometric functions, and how to evaluate them. this document is only meant to be a very quick reminder. Learn to evaluate trigonometric functions of any angle using the unit circle, reference angles, and general definitions. includes examples and solutions. Directions: find the exact value of each trigonometric function. find the reference angle, quadrant, and then decide if the trig function is positive or negative in that quadrant.

Directions: find the exact value of each trigonometric function. find the reference angle, quadrant, and then decide if the trig function is positive or negative in that quadrant. 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. Let's see how this corollary, along with focusing on reference angles and quadrants, speeds up the evaluation of trigonometric functions whose reference angles are the special angles. Signs of trig functions table of contents signs of trig functions using reference angles examples with degrees examples with radians last example. Find reference angle . evaluate from table s a 26 . use original quad to find sign t . reciprocate if needed ex. evaluate the trigonometric function of each angle.
