    Answer:

    Find that the terminal side lands in quadrant III.

    The angle is coterminal with a 210° angle.

    The reference angle is 30°.

    The sine of 30° is 1/2.

    Sine is negative in quadrant III.

    The sine of 570° is –1/2.

    Answer: Sin(570) = – 1/2

    Step-by-step explanation:

    570 as an angle contains 1 complete revolution of the terminal arm. The terminal arm begins at the origin and the other (in this case swings around until it records 570° turning around the x axis in an anticlockwise direction.
