Question

Find the value of given trigonometric function cot (-330°)

Answer 1

The exact value should be

`√(3)`

Explanation:

Though you can get this directly out from your calculator, but you can utilize the opposite angle identities, cot(-

θ)=-cot θ, then use the trig identity, which is

`\cot(θ) = ( \cos(θ) )/( \sin(θ) )`

So cot (-330)=cos (-330)/sin (-330)
