- \sin (15 °)

-\sin(15\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\sin (195 °) = \sin (360 - 165 °)$

The period of trigonometric functions is 360 degrees.

$\sin (360 - 165 °) = \sin (360 - 165 - 360 °)$

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

$\sin (360 - 165 - 360 °) = \sin (- 165 °)$

Computing the sine of a negative angle.

$\sin (- 165 °) = - \sin (165 °)$

Reflecting the number with respect to 360 degrees.

$- \sin (165 °) = - \sin (180 - 15 °)$

Reflecting the sine function with respect to 180 degrees.

$- \sin (180 - 15 °) = - \sin (15 °)$
