Question

Find the exact values below. if applicable click on undefined cot(11pi/6)

Answer 1

We have to find the exact value of

`cot( (11 \pi)/(6) )`

And it can also be written as

`cot(2 \pi - ( \pi )/(6) )`

And

`cot(2 \pi - \theta) = - cot \theta`

So we will get

`cot(2 \pi -  ( \pi)/(6) ) = -cot( ( \pi )/(6)) = - \sqrt 3`
