Question

What are the six trig function values of `330`?

Answer 1

`cos 330 = cos (-30 + 360) = cos (-30) = cos 30 = sqrt3/2`
`sin 330 = sin (-30 + 360) = sin (-30) = - sin 30 = - 1/2`
`tan 330 = sin/9cos) = (-1/2)(2/sqrt3) = - 1/sqrt3 = - sqrt3/3`
`cot 330 = 1/(tan) = - 3/sqrt3 = -sqrt3`
`sec 330 = 1/(cos) = 2/sqrt3 = 2sqrt3/3`
`csc 330 =1/(sin) = - 2`
