\cos (180 °)

\cos(180\degree)

Vysvětlení krok za krokem

The period of trigonometric functions is 360 degrees.

$\cos (1260 °) = \cos (1260 - 360 °)$

Subtracting one integer from another.

$\cos (1260 - 360 °) = \cos (900 °)$

The period of trigonometric functions is 360 degrees.

$\cos (900 °) = \cos (900 - 360 °)$

Subtracting one integer from another.

$\cos (900 - 360 °) = \cos (540 °)$

The period of trigonometric functions is 360 degrees.

$\cos (540 °) = \cos (540 - 360 °)$

Subtracting one integer from another.

$\cos (540 - 360 °) = \cos (180 °)$
