WebbTrigonometric 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].
