Question

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

Answer 1

We have to find the exact value of

$cot( \frac{11 \pi}{6} )$

And it can also be written as

$cot(2 \pi - \frac{ \pi }{6} )$

And

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

So we will get

$cot(2 \pi -  \frac{ \pi}{6} ) = -cot( \frac{ \pi }{6}) = - \sqrt 3$
