The domain of the sine function is (−∞<θ<∞).
We need to find the domain of the sine function.
What is the sine function?
In trigonometry, the sine function can be defined as the ratio of the length of the opposite side to that of the hypotenuse in a right-angled triangle.
The domain of a function is the set of input values for which the function is real and defined.
(−∞<θ<∞)
Domain restriction is used for the sine Graph to display one complete cycle.
Range: The set of output values (of the dependent variable) for which the function is defined.
As you can easily observe, the sine graph goes up until 1 and goes down until −1.
(−1<θ<1)
Therefore, the domain of the sine function is (−∞<θ<∞).
