\tan (\frac{5 π}{6})

$\tan (\frac{5 π}{6})$

Step 1

Apply the reference angle by finding the angle with equivalent trig values in the first quadrant. Make the expression negative because tangent is negative in the second quadrant.

- \tan (\frac{π}{6})

$- \tan (\frac{π}{6})$

Step 2

The exact value of

\tan (\frac{π}{6})

$\tan (\frac{π}{6})$ is

\frac{\sqrt{3}}{3}

$\frac{\sqrt{3}}{3}$ .

- \frac{\sqrt{3}}{3}

$- \frac{\sqrt{3}}{3}$

Step 3

The result can be shown in multiple forms.

Exact Form:

- \frac{\sqrt{3}}{3}

$- \frac{\sqrt{3}}{3}$

Decimal Form:

- 0.57735026 \dots

$- 0.57735026 \dots$
