1+sqrt(3)tan((2x-pi)/3)=0

Solution

1 + 3 tan (\frac{2 x - π}{3}) = 0

Solution

x = \frac{π}{2} + \frac{5 π}{4} + \frac{3 πn}{2}

Degrees

x = 31 5^{\circ} + 27 0^{\circ} n

Solution steps

1 + 3 tan (\frac{2 x - π}{3}) = 0

Move

1

to the right side

1 + 3 tan (\frac{2 x - π}{3}) = 0

Subtract

1

from both sides

1 + 3 tan (\frac{2 x - π}{3}) - 1 = 0 - 1

Simplify

3 tan (\frac{2 x - π}{3}) = - 1

3 tan (\frac{2 x - π}{3}) = - 1

Divide both sides by

3

3 tan (\frac{2 x - π}{3}) = - 1

Divide both sides by

3

\frac{3 tan ( \frac{2 x - π}{3} )}{3} = \frac{- 1}{3}

Simplify

\frac{3 tan ( \frac{2 x - π}{3} )}{3} = \frac{- 1}{3}

Simplify

\frac{3 tan ( \frac{2 x - π}{3} )}{3} : tan (\frac{2 x - π}{3})

\frac{3 tan ( \frac{2 x - π}{3} )}{3}

Cancel the common factor:

3

= tan (\frac{2 x - π}{3})

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}

tan (\frac{2 x - π}{3}) = - \frac{3}{3}

tan (\frac{2 x - π}{3}) = - \frac{3}{3}

tan (\frac{2 x - π}{3}) = - \frac{3}{3}

\frac{2 x - π}{3} = \frac{5 π}{6} + πn

\frac{2 x - π}{3} = \frac{5 π}{6} + πn

Solve

\frac{2 x - π}{3} = \frac{5 π}{6} + πn : x = \frac{π}{2} + \frac{5 π}{4} + \frac{3 πn}{2}

\frac{2 x - π}{3} = \frac{5 π}{6} + πn

Multiply both sides by

3

\frac{2 x - π}{3} = \frac{5 π}{6} + πn

Multiply both sides by

\frac{3 ( 2 x - π )}{3} = 3 \cdot \frac{5 π}{6} + 3 πn

Simplify

\frac{3 ( 2 x - π )}{3} = 3 \cdot \frac{5 π}{6} + 3 πn

Simplify

\frac{3 ( 2 x - π )}{3} : 2 x - π

\frac{3 ( 2 x - π )}{3}

Divide the numbers:

\frac{3}{3} = 1

= 2 x - π

Simplify

3 \cdot \frac{5 π}{6} + 3 πn : \frac{5 π}{2} + 3 πn

3 \cdot \frac{5 π}{6} + 3 πn

3 \cdot \frac{5 π}{6} = \frac{5 π}{2}

3 \cdot \frac{5 π}{6}

Multiply fractions:

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

= \frac{5 π 3}{6}

Multiply the numbers:

5 \cdot 3 = 15

= \frac{15 π}{6}

Cancel the common factor:

3

= \frac{5 π}{2}

= \frac{5 π}{2} + 3 πn

2 x - π = \frac{5 π}{2} + 3 πn

2 x - π = \frac{5 π}{2} + 3 πn

2 x - π = \frac{5 π}{2} + 3 πn

Move

π

to the right side

2 x - π = \frac{5 π}{2} + 3 πn

Add

π

to both sides

2 x - π + π = \frac{5 π}{2} + 3 πn + π

Simplify

2 x = \frac{5 π}{2} + 3 πn + π

2 x = \frac{5 π}{2} + 3 πn + π

Divide both sides by

2

2 x = \frac{5 π}{2} + 3 πn + π

Divide both sides by

\frac{2 x}{2} = \frac{\frac{5 π}{2}}{2} + \frac{3 πn}{2} + \frac{π}{2}

Simplify

\frac{2 x}{2} = \frac{\frac{5 π}{2}}{2} + \frac{3 πn}{2} + \frac{π}{2}

Simplify

\frac{2 x}{2} : x

\frac{2 x}{2}

Divide the numbers:

\frac{2}{2} = 1

= x

Simplify

\frac{\frac{5 π}{2}}{2} + \frac{3 πn}{2} + \frac{π}{2} : \frac{π}{2} + \frac{5 π}{4} + \frac{3 πn}{2}

\frac{\frac{5 π}{2}}{2} + \frac{3 πn}{2} + \frac{π}{2}

Group like terms

= \frac{π}{2} + \frac{3 πn}{2} + \frac{\frac{5 π}{2}}{2}

\frac{\frac{5 π}{2}}{2} = \frac{5 π}{4}

\frac{\frac{5 π}{2}}{2}

Apply the fraction rule:

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

= \frac{5 π}{2 \cdot 2}

Multiply the numbers:

2 \cdot 2 = 4

= \frac{5 π}{4}

= \frac{π}{2} + \frac{3 πn}{2} + \frac{5 π}{4}

Group like terms

= \frac{π}{2} + \frac{5 π}{4} + \frac{3 πn}{2}

x = \frac{π}{2} + \frac{5 π}{4} + \frac{3 πn}{2}
