sqrt(3)cot(2x)+3=0

Solution

3 cot (2 x) + 3 = 0

Solution

x = \frac{5 π}{12} + \frac{πn}{2}

Degrees

x = 7 5^{\circ} + 9 0^{\circ} n

Solution steps

3 cot (2 x) + 3 = 0

Move

3

to the right side

3 cot (2 x) + 3 = 0

Subtract

3

from both sides

3 cot (2 x) + 3 - 3 = 0 - 3

Simplify

3 cot (2 x) = - 3

3 cot (2 x) = - 3

Divide both sides by

3

3 cot (2 x) = - 3

Divide both sides by

3

\frac{3 cot ( 2 x )}{3} = \frac{- 3}{3}

Simplify

\frac{3 cot ( 2 x )}{3} = \frac{- 3}{3}

Simplify

\frac{3 cot ( 2 x )}{3} : cot (2 x)

\frac{3 cot ( 2 x )}{3}

Cancel the common factor:

3

= cot (2 x)

Simplify

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

\frac{- 3}{3}

Apply the fraction rule:

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

= - \frac{3}{3}

Apply radical rule:

n a = a^{\frac{1}{n}}

3 = 3^{\frac{1}{2}}

= \frac{3}{3 ^{\frac{1}{2}}}

Apply exponent rule:

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

\frac{3 ^{1}}{3 ^{\frac{1}{2}}} = 3^{1 - \frac{1}{2}}

= 3^{1 - \frac{1}{2}}

Subtract the numbers:

1 - \frac{1}{2} = \frac{1}{2}

= 3^{\frac{1}{2}}

Apply radical rule:

a^{\frac{1}{n}} = n a

3^{\frac{1}{2}} = 3

= - 3

cot (2 x) = - 3

cot (2 x) = - 3

cot (2 x) = - 3

2 x = \frac{5 π}{6} + πn

2 x = \frac{5 π}{6} + πn

Solve

2 x = \frac{5 π}{6} + πn : x = \frac{5 π}{12} + \frac{πn}{2}

2 x = \frac{5 π}{6} + πn

Divide both sides by

2

2 x = \frac{5 π}{6} + πn

Divide both sides by

2

\frac{2 x}{2} = \frac{\frac{5 π}{6}}{2} + \frac{πn}{2}

Simplify

\frac{2 x}{2} = \frac{\frac{5 π}{6}}{2} + \frac{πn}{2}

Simplify

\frac{2 x}{2} : x

\frac{2 x}{2}

Divide the numbers:

\frac{2}{2} = 1

= x

Simplify

\frac{\frac{5 π}{6}}{2} + \frac{πn}{2} : \frac{5 π}{12} + \frac{πn}{2}

\frac{\frac{5 π}{6}}{2} + \frac{πn}{2}

\frac{\frac{5 π}{6}}{2} = \frac{5 π}{12}

\frac{\frac{5 π}{6}}{2}

Apply the fraction rule:

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

= \frac{5 π}{6 \cdot 2}

Multiply the numbers:

6 \cdot 2 = 12

= \frac{5 π}{12}

= \frac{5 π}{12} + \frac{πn}{2}

x = \frac{5 π}{12} + \frac{πn}{2}

x = \frac{5 π}{12} + \frac{πn}{2}

x = \frac{5 π}{12} + \frac{πn}{2}

x = \frac{5 π}{12} + \frac{πn}{2}
