Josiah AndersonTo evaluate cot((5π)/6), first find the sine and cosine of the angle.
sin((5π)/6) = 1/2 cos((5π)/6) = -√3/2
Then, use the definition of cotangent: cot(x) = cos(x)/sin(x).
cot((5π)/6) = (cos((5π)/6)) / (sin((5π)/6)) = (-√3/2) / (1/2) = -√3

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
