Answer:

The function is undefined whenever

x=2πn and x=π+2πn where n is an integer.

Explanation:

Cot(x) = cos(x) / sin(x)

Since a/0 is undefined for each and every value of a, we want to find the points were sin(x) = 0.

Sin(x) = 0

x = sin-1(0)

x = 0, π

Since trig functions are periodic, that's to say

they go to infinity in both directions, we want to

find a general form solution.

The period of sin(x) is 2π

x=2πn and π+2πn , where n is an integer.
