In this module, you will explore the properties of key angles in all quadrants of the unit circle measured in both degrees and radians to compute the values of the six trigonometric functions: sine, cosine, tangent, secant, cosecant, and cotangent functions. Evaluate the six trigonometric functions of θ. find r. now use the trigonometric formulas. if (4, −8) is a point on the terminal side of angle α in standard position, evaluate the six trigonometric functions of α. evaluate cos 270° and csc π. 270° and π radians terminal sides are both on an axis. Now that we have learned how to find the cosine and sine values for special angles in the first quadrant, we can use symmetry and reference angles to fill in cosine and sine values for the rest of the special angles on the unit circle. Definition the reference angle of the angle , denoted by ' , is the acute angle determined by the terminal side of and either the positive or negative x axis. recall, an acute angle is an angle whose measurement is greater than 0 and less than 90 . note: by definition, the reference angle is an acute angle.
