What is the range of the function y=cotx? Precalculus Functions Defined and Notation Range 1 Answer Aritra G. · Stefan V. Jul 22, 2015 Range of cotx is (−∞,+∞) Explanation: The cotangent function can take up any values depending on the value of x , the independent variable. And thus, the range (−∞,+∞) is justified. The domain is all real numbers other than integral multiples of π where, the function is not defined. Answer link Related questions What is the range of a function? What are some examples of range?
