- \sin (75 °)

-\sin(75\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\sin (255 °) = \sin (360 - 105 °)$

The period of trigonometric functions is 360 degrees.

$\sin (360 - 105 °) = \sin (360 - 105 - 360 °)$

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

$\sin (360 - 105 - 360 °) = \sin (- 105 °)$

Computing the sine of a negative angle.

$\sin (- 105 °) = - \sin (105 °)$

Reflecting the number with respect to 360 degrees.

$- \sin (105 °) = - \sin (180 - 75 °)$

Reflecting the sine function with respect to 180 degrees.

$- \sin (180 - 75 °) = - \sin (75 °)$
