- \tan (82 °)

-\tan(82\degree)

Vysvětlení krok za krokem

Reflecting the number with respect to 360 degrees.

$\tan (98 °) = \tan (180 - 82 °)$

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

$\tan (180 - 82 °) = \frac{\sin (180 - 82 °)}{\cos (180 - 82 °)}$

Reflecting the sine function with respect to 180 degrees.

$\frac{\sin (180 - 82 °)}{\cos (180 - 82 °)} = \frac{\sin (82 °)}{\cos (180 - 82 °)}$

Reflecting the cosine function with respect to 180 degrees.

$\frac{\sin (82 °)}{\cos (180 - 82 °)} = \frac{\sin (82 °)}{- \cos (82 °)}$

Placing the minus sign in front of a fraction.

$\frac{\sin (82 °)}{- \cos (82 °)} = - \frac{\sin (82 °)}{\cos (82 °)}$

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

$- \frac{\sin (82 °)}{\cos (82 °)} = - \tan (82 °)$
