- \sin (20 °)

-\sin(20\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\sin (200 °) = \sin (360 - 160 °)$

The period of trigonometric functions is 360 degrees.

$\sin (360 - 160 °) = \sin (360 - 160 - 360 °)$

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

$\sin (360 - 160 - 360 °) = \sin (- 160 °)$

Computing the sine of a negative angle.

$\sin (- 160 °) = - \sin (160 °)$

Reflecting the number with respect to 360 degrees.

$- \sin (160 °) = - \sin (180 - 20 °)$

Reflecting the sine function with respect to 180 degrees.

$- \sin (180 - 20 °) = - \sin (20 °)$
