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

Solution

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

Solution

x = \frac{5 π}{3} + 2 πn

Degrees

x = 30 0^{\circ} + 36 0^{\circ} n

Solution steps

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

Move

1

to the right side

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

Subtract

1

from both sides

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

Simplify

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

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

Divide both sides by

3

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

Divide both sides by

3

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

Simplify

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

Simplify

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

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

Cancel the common factor:

3

= tan (\frac{x}{2})

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

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

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

\frac{x}{2} = \frac{5 π}{6} + πn

\frac{x}{2} = \frac{5 π}{6} + πn

Solve

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

\frac{x}{2} = \frac{5 π}{6} + πn

Multiply both sides by

2

\frac{x}{2} = \frac{5 π}{6} + πn

Multiply both sides by

2

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

Simplify

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

Simplify

\frac{2 x}{2} : x

\frac{2 x}{2}

Divide the numbers:

\frac{2}{2} = 1

= x

Simplify

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

2 \cdot \frac{5 π}{6} + 2 πn

2 \cdot \frac{5 π}{6} = \frac{5 π}{3}

2 \cdot \frac{5 π}{6}

Multiply fractions:

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

= \frac{5 π 2}{6}

Multiply the numbers:

5 \cdot 2 = 10

= \frac{10 π}{6}

Cancel the common factor:

= \frac{5 π}{3}

= \frac{5 π}{3} + 2 πn

x = \frac{5 π}{3} + 2 πn

x = \frac{5 π}{3} + 2 πn

x = \frac{5 π}{3} + 2 πn

x = \frac{5 π}{3} + 2 πn
