The domain and range of cosine are given by: Domain = All real numbers, i.e., (−∞, ∞) Range = [-1, 1]

9 мар. 2017 г. · The Range of Cosine is from [-1,1] or that is -1 to +1 both included. What is the range of cosine x? What is the range of f(x): a cos(x) +b sin(x)? What is the range of cos |x|? What is the range of cos (sin x)? Другие результаты с сайта www.quora.com

Domain and Range of Cosine Function {Cos (θ)} The cosine function cos(θ) also has a domain of all real numbers and a range between -1 and 1: -1 ≤ cos(θ) ≤ 1.

The domain of the function y = cos ( x ) is all real numbers (cosine is defined for any angle measure), the range is − 1 ≤ y ≤ 1 .

Notice, however, that the range for both y = sin(x) and y = cos(x) is between -1 and 1.
