1. what is the domain of validity for csc theta=1/sin theta? a. all real numbers b. all real numbers except odd multiples of pi/2 c. all real numbers except even multiples of pi/2 d. all real numbers except multiples of pi

Option D. All real numbers except multiples of pi

Step-by-step explanation:

It has been given that and we have to find the domain of the given expression.

As we know is defined only when or but not equal to zero.

Since sine of are always zero. Therefore domain of is

That means Option D. All real numbers except multiples of pi is the answer.
