Question

What is the range of the function y= cot(x)?

Answer 1

I believe its A, just all real numbers

Answer 2

Answer:

all real numbers

Step-by-step explanation:

Given : y = cot(x)

To Find: Range.

Solution:

Refer the attached graph.

The domain of the function   $y=cot(x)=\frac{cos(x)}{sin(x)}$   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.
