Question

How to you find the cotangent of 5(pi)/6?

Answer 1

To find the cotangent you need to know the points of
`(5)/(6)\pi`, which is
`(-(√(3))/(2), (1)/(2) )` One sec more is coming. Now that you know the (x, y) point, you can use the function cot, which cot =
`(x)/(y)`. So
cot =
`(-(√(3))/(2))/((1)/(2))`

cot =
`(-(√(3))/(2))/((1)/(2)) = -√(3)`
