Question

What is the exact value of the trigonometric expression? sin(5π/6)

Answer 1

`(1)/(2)`

Explanation:

Answer 2

sin(5π/6) =
`(1)/(2)`

Explanation:

The given angle 5π/6 lies at the third quarter

because: (π/2) < (5π/6) < π

The sin at this quarter is +ve

sin(5π/6) = sin ( π - π/6) = sin (π/6) = 1/2
