-\frac{\sqrt{3}}{2}

Vysvětlení krok za krokem

The period of trigonometric functions is 360 degrees.

$\sin (660 °) = \sin (660 - 360 °)$

Subtracting one integer from another.

$\sin (660 - 360 °) = \sin (300 °)$

Reflecting the number with respect to 360 degrees.

$\sin (300 °) = \sin (360 - 60 °)$

The period of trigonometric functions is 360 degrees.

$\sin (360 - 60 °) = \sin (360 - 60 - 360 °)$

Removing or simplifying the same numbers on the top and bottom of a fraction.

$\sin (360 - 60 - 360 °) = \sin (- 60 °)$

Computing the sine of a negative angle.

$\sin (- 60 °) = - \sin (60 °)$

Computing the sine of 60 degrees.

$- \sin (60 °) = - \frac{\sqrt{3}}{2}$
