Question

What are the six trig function values of `(7pi)/6`?

Answer 1

Trig Table of Special Arcs and unit circle -->
`sin (7pi)/6 = sin (pi/6 + pi) = - sin pi/6 = - 1/2`
`cos (7pi)/6 = cos (pi/6 + pi) = - cos pi/6 = -sqrt3/2`
`tan pi/6 = sin/(cos) = 1/sqrt3 = sqrt3/3`
`cot = 1/(tan) = sqrt3`
`sec = 1/(cos) = -2/sqrt3 = - 2sqrt3/3`
`csc = 1/(sin) = -2`
