sqrt(3)cot(1/3 x)=1

Solution

3 cot (\frac{1}{3} x) = 1

Solution

x = π + 3 πn

Degrees

x = 18 0^{\circ} + 54 0^{\circ} n

Solution steps

3 cot (\frac{1}{3} x) = 1

Divide both sides by

3

3 cot (\frac{1}{3} x) = 1

Divide both sides by

3

\frac{3 cot ( \frac{1}{3} x )}{3} = \frac{1}{3}

Simplify

\frac{3 cot ( \frac{1}{3} x )}{3} = \frac{1}{3}

Simplify

\frac{3 cot ( \frac{1}{3} x )}{3} : cot (\frac{1}{3} x)

\frac{3 cot ( \frac{1}{3} x )}{3}

Cancel the common factor:

3

= cot (\frac{1}{3} x)

Simplify

\frac{1}{3} : \frac{3}{3}

\frac{1}{3}

Multiply by the conjugate

\frac{3}{3}

= \frac{1 \cdot 3}{3 3}

1 \cdot 3 = 3

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= \frac{3}{3}

cot (\frac{1}{3} x) = \frac{3}{3}

cot (\frac{1}{3} x) = \frac{3}{3}

cot (\frac{1}{3} x) = \frac{3}{3}

\frac{1}{3} x = \frac{π}{3} + πn

\frac{1}{3} x = \frac{π}{3} + πn

Solve

\frac{1}{3} x = \frac{π}{3} + πn : x = π + 3 πn

\frac{1}{3} x = \frac{π}{3} + πn

Multiply both sides by

3

\frac{1}{3} x = \frac{π}{3} + πn

Multiply both sides by

3

3 \cdot \frac{1}{3} x = 3 \cdot \frac{π}{3} + 3 πn

Simplify

3 \cdot \frac{1}{3} x = 3 \cdot \frac{π}{3} + 3 πn

Simplify

3 \cdot \frac{1}{3} x : x

3 \cdot \frac{1}{3} x

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{1 \cdot 3}{3} x

Cancel the common factor:

3

= x \cdot 1

Multiply:

x \cdot 1 = x

= x

Simplify

3 \cdot \frac{π}{3} + 3 πn : π + 3 πn

3 \cdot \frac{π}{3} + 3 πn

3 \cdot \frac{π}{3} = π

3 \cdot \frac{π}{3}

Multiply fractions:

a \cdot \frac{b}{c} = \frac{a \cdot b}{c}

= \frac{π 3}{3}

Cancel the common factor:

3

= π

= π + 3 πn

x = π + 3 πn

x = π + 3 πn

x = π + 3 πn

x = π + 3 πn
