sqrt(3)csc(x/2)-2=0

Solution

3 csc (\frac{x}{2}) - 2 = 0

Solution

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

Degrees

x = 12 0^{\circ} + 72 0^{\circ} n, x = 24 0^{\circ} + 72 0^{\circ} n

Solution steps

3 csc (\frac{x}{2}) - 2 = 0

Move

2

to the right side

3 csc (\frac{x}{2}) - 2 = 0

Add

2

to both sides

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

Simplify

3 csc (\frac{x}{2}) = 2

3 csc (\frac{x}{2}) = 2

Divide both sides by

3

3 csc (\frac{x}{2}) = 2

Divide both sides by

3

\frac{3 csc ( \frac{x}{2} )}{3} = \frac{2}{3}

Simplify

\frac{3 csc ( \frac{x}{2} )}{3} = \frac{2}{3}

Simplify

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

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

Cancel the common factor:

3

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

Simplify

\frac{2}{3} : \frac{2 3}{3}

\frac{2}{3}

Multiply by the conjugate

\frac{3}{3}

= \frac{2 3}{3 3}

33 = 3

33

Apply radical rule:

a a = a

33 = 3

= 3

= \frac{2 3}{3}

csc (\frac{x}{2}) = \frac{2 3}{3}

csc (\frac{x}{2}) = \frac{2 3}{3}

csc (\frac{x}{2}) = \frac{2 3}{3}
