sqrt(3)cot(x)=-1

3 cot (x) = - 1

x = \frac{2 π}{3} + πn

Degrees

x = 12 0^{\circ} + 18 0^{\circ} n

Solution steps

3 cot (x) = - 1

Divide both sides by

3

3 cot (x) = - 1

Divide both sides by

3

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

Simplify

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

Simplify

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

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

Cancel the common factor:

3

= cot (x)

Simplify

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

\frac{- 1}{3}

Apply the fraction rule:

\frac{- a}{b} = - \frac{a}{b}

= - \frac{1}{3}

Rationalize

- \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}

= - \frac{3}{3}

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

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

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

General solutions for

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

cot (x)

periodicity table with

πn

cycle:

x = \frac{2 π}{3} + πn

x = \frac{2 π}{3} + πn

cos^{2} (\frac{x}{2}) = cos^{2} (x)

sin (2 x) - 1 = 0

csc (θ) = 1

2 cos (x) = - 1

sin (\frac{x}{2}) = 1 - sin (\frac{x}{2})
