Domain Function Of Sine
If theta represents all the angles in the domain of the two functions.
Domain function of sine. Y cos x is an even function which implies it is symmetric about the y axis. Cos x 1 1 hence for the trigonometric functions f x sin x and f x cos x the domain will consist of the entire set of real numbers as they are defined for all the real numbers. Ranges of sine and cosine.
They are periodic functions with a period of 2π. In trig speak you say something like this. The graph of y sin x is symmetric about the origin because it s an odd function.
Cos 2 x 1. Sin x 1 1 hence we got the range and domain for sine function. The domains of sine and cosine are infinite.
Which means that theta can be any angle in degrees or radians any real number. The domain of each function is and the range is 1 1. This trigonometry video tutorial explains how to find the domain and range of trigonometric functions such as sine cosine secant cosecant tangent and co.
