Find the domain of the function:
The function is related to the parent function , which has a domain of .
The value of theta for has no restriction and is valid for all real numbers.
The answer is .
Example Question #7 : Sine
What is the domain of the given trigonometric function:
For both Sine and Cosine, since there are no asymptotes like Tangent and Cotangent functions, the function can take in any value for . Thus the domain is:
