What is the domain of y = cot x?
a. (- ∞ ,∞ )
b.(0,π)
c. all x≠ π/2+π
d. all x≠ π
e. all x≠ π/2

The domain of y=cot x is:

               Option: b

                b.     (0,π)

We know that a domain of a function is the set of all the possible x values for which the function is well defined.

We are given a function as:

which is further defined as:

Hence, the function is well defined when the denominator term is non-zero.

We know that the denominator term i.e. the sine function is zero at the points:

Hence, the best possible option is:

           b.   (0,π)

option: d is the correct answer.

d) none of the above.

step-by-step explanation:

clearly from the figure attached to the question we could see that there is no shape given. hence without any shape given in the figure and after rotation we can't obtained a square pyramid.

since, to obtain a image we need a proper figure of the pre-image so that it can be transformed.

hence, the correct answer is:

d) none of the above.
