Find the Value Using the Unit Circle cot(300)

$\cot (300)$

Find the value using the definition of cotangent.

$\cot (300) = \frac{adjacent}{opposite}$

Substitute the values into the definition.

$\cot (300) = \frac{\frac{1}{2}}{- \frac{\sqrt{3}}{2}}$

Simplify the result.

Multiply the numerator by the reciprocal of the denominator.

$\frac{1}{2} (- \frac{2}{\sqrt{3}})$

Cancel the common factor of $2$ .

Move the leading negative in $- \frac{2}{\sqrt{3}}$ into the numerator.

$\frac{1}{2} \cdot \frac{- 2}{\sqrt{3}}$

Factor $2$ out of $- 2$ .

$\frac{1}{2} \cdot \frac{2 (- 1)}{\sqrt{3}}$

Cancel the common factor.

$\frac{1}{2} \cdot \frac{2 \cdot - 1}{\sqrt{3}}$

Rewrite the expression.

$\frac{- 1}{\sqrt{3}}$

Move the negative in front of the fraction.

$- \frac{1}{\sqrt{3}}$

Multiply $\frac{1}{\sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

$- (\frac{1}{\sqrt{3}} \cdot \frac{\sqrt{3}}{\sqrt{3}})$

Combine and simplify the denominator.

Multiply $\frac{1}{\sqrt{3}}$ by $\frac{\sqrt{3}}{\sqrt{3}}$ .

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

Raise $\sqrt{3}$ to the power of $1$ .

$- \frac{\sqrt{3}}{{\sqrt{3}}^{1} \sqrt{3}}$

Raise $\sqrt{3}$ to the power of $1$ .

$- \frac{\sqrt{3}}{{\sqrt{3}}^{1} {\sqrt{3}}^{1}}$

Use the power rule $a^{m} a^{n} = a^{m + n}$ to combine exponents.

$- \frac{\sqrt{3}}{{\sqrt{3}}^{1 + 1}}$

Add $1$ and $1$ .

$- \frac{\sqrt{3}}{{\sqrt{3}}^{2}}$

Rewrite ${\sqrt{3}}^{2}$ as $3$ .

Use $\sqrt[n]{a^{x}} = a^{\frac{x}{n}}$ to rewrite $\sqrt{3}$ as $3^{\frac{1}{2}}$ .

$- \frac{\sqrt{3}}{{(3^{\frac{1}{2}})}^{2}}$

Apply the power rule and multiply exponents, ${(a^{m})}^{n} = a^{m n}$ .

$- \frac{\sqrt{3}}{3^{\frac{1}{2} \cdot 2}}$

Combine $\frac{1}{2}$ and $2$ .

$- \frac{\sqrt{3}}{3^{\frac{2}{2}}}$

Cancel the common factor of $2$ .

Cancel the common factor.

$- \frac{\sqrt{3}}{3^{\frac{2}{2}}}$

Rewrite the expression.

$- \frac{\sqrt{3}}{3^{1}}$

Evaluate the exponent.

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

The result can be shown in multiple forms.

Exact Form:

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

Decimal Form:

$- 0.57735026 \dots$
