What is the range of the function y= cot(x)? a. all real numbers b. all real numbers except pi/2 + n(pi), where n is any integer c. all real numbers except n(pi)/2, where n is any integer d. all real numbers except n(pi), where n is any integer

all real numbers

Step-by-step explanation:

Given : y = cot(x)

To Find: Range.

Solution:

Refer the attached graph.

The domain of the function     is all real numbers except the values where sin(x) is equal to 0 , that is, the values πn for all integers n .  

The range of the function is all real numbers.

Referring the graph we can say that the range of the given function y = cot(x) is all real numbers .

Hence Option A is correct.
