Introduction to the domain and range of a function. Examples: (3;11) ( 3; 11) Round brackets indicate that the number is not included. B. Tangent 1. The range of the tangent function is (Type your answer in interval notation.) (c)The inverse tangent has a domain of R, and a range if. Once the range for Arctan is defined, there's really only one sensible way to define Arccot: cot x = tan (/2 x ) Arccot x = /2 Arctan x which gives the single open interval (0, ) or (0, 180) as the range. See (Figure). Answer (1 of 4): Domain: (k/2, where k is an odd integer) Range: (,) Explanation: Remember that tan=sin/cos therefore, you will have a vertical asymptope whenever cos=0. Square roots break if there is a negative value under the root. The secant function has vertical asymptotes at points where the cosine function is equal to zero. The endpoint values are listed between brackets or parentheses. Range - Precalculus | Socratic We can write the domain and range in interval notation, which uses values within brackets to describe a set of numbers. For the following exercises, write the domain and range of each function using interval notation.Here are all of our Math Playlists:Functions:Functions and.
