Question

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

Answer 1

Answer:

The exact value should be

$\sqrt{3}$

Step-by-step 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

$\cot(θ) = \frac{ \cos(θ) }{ \sin(θ) }$

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