WebIf one angle is an reference angle of another, the trigonometric functions of these two angles have the same values in magnitude, and we just need to pay attention to their signs based on the quadrant that the terminal side of the angle lies in. For example, 30° is the reference angle of 210° with sine values sin(30°)= and sin(210°)=. WebTrigonometric Functions. Trigonometric functions are the basic six functions that have a domain input value as an angle of a right triangle, and a numeric answer as the range.The trigonometric function (also called the 'trig function') of f(x) = sinθ has a domain, which is the angle θ given in degrees or radians, and a range of [-1, 1].
