Question

cot (-pi/3)

Answer 1

Have you considered an equivalent expression in terms of sine and cosine?

Answer 2

yes, I am having trouble solving it

Answer 3

Let's see your sine and cosine version.

Answer 4

cos= 2squarroot 3/3

Answer 5

I was hoping for this: \(\cot(-\pi/3) = \dfrac{\cos(-\pi/3)}{\sin(-\pi/3)}\)

Answer 6

so is it the square root of 3/3

Answer 7

Simplest thing is to say that the cot is the reciprocal of the tangent. Tangent of pi/3=sqrt3. cotangent is 1/sqrt3=sqrt3/3
