- \tan (63 °)

-\tan(63\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\tan (117 °) = \tan (180 - 63 °)$

The tangent of an angle is equal to the sine of the angle divided by the cosine of the angle.

$\tan (180 - 63 °) = \frac{\sin (180 - 63 °)}{\cos (180 - 63 °)}$

Reflecting the sine function with respect to 180 degrees.

$\frac{\sin (180 - 63 °)}{\cos (180 - 63 °)} = \frac{\sin (63 °)}{\cos (180 - 63 °)}$

Reflecting the cosine function with respect to 180 degrees.

$\frac{\sin (63 °)}{\cos (180 - 63 °)} = \frac{\sin (63 °)}{- \cos (63 °)}$

Placing the minus sign in front of a fraction.

$\frac{\sin (63 °)}{- \cos (63 °)} = - \frac{\sin (63 °)}{\cos (63 °)}$

The tangent of an angle is equal to the sine of the angle divided by the cosine of the angle.

$- \frac{\sin (63 °)}{\cos (63 °)} = - \tan (63 °)$
