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

Answer 1

Answer:

sin(5π/6) = $\frac{1}{2}$

Step-by-step 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

See the attached figure.
