- \sin (65 °)

-\sin(65\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\sin (245 °) = \sin (360 - 115 °)$

The period of trigonometric functions is 360 degrees.

$\sin (360 - 115 °) = \sin (360 - 115 - 360 °)$

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

$\sin (360 - 115 - 360 °) = \sin (- 115 °)$

Computing the sine of a negative angle.

$\sin (- 115 °) = - \sin (115 °)$

Reflecting the number with respect to 360 degrees.

$- \sin (115 °) = - \sin (180 - 65 °)$

Reflecting the sine function with respect to 180 degrees.

$- \sin (180 - 65 °) = - \sin (65 °)$
