2tan(x)sin(x)=sqrt(3)tan(x)

Solution

2 tan (x) sin (x) = 3 tan (x)

Solution

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

Degrees

x = 0^{\circ} + 18 0^{\circ} n, x = 6 0^{\circ} + 36 0^{\circ} n, x = 12 0^{\circ} + 36 0^{\circ} n

Solution steps

2 tan (x) sin (x) = 3 tan (x)

Subtract

3 tan (x)

from both sides

2 tan (x) sin (x) - 3 tan (x) = 0

Factor

2 tan (x) sin (x) - 3 tan (x) : tan (x) (2 sin (x) - 3)

2 tan (x) sin (x) - 3 tan (x)

Factor out common term

tan (x)

= tan (x) (2 sin (x) - 3)

tan (x) (2 sin (x) - 3) = 0

Solving each part separately

tan (x) = 0 or 2 sin (x) - 3 = 0

tan (x) = 0 : x = πn

tan (x) = 0

tan (x) = 0

x = 0 + πn

x = 0 + πn

Solve

x = 0 + πn : x = πn

x = 0 + πn

0 + πn = πn

x = πn

x = πn

2 sin (x) - 3 = 0 : x = \frac{π}{3} + 2 πn, x = \frac{2 π}{3} + 2 πn

2 sin (x) - 3 = 0

Move

3

to the right side

2 sin (x) - 3 = 0

Add

3

to both sides

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

Simplify

2 sin (x) = 3

2 sin (x) = 3

Divide both sides by

2

2 sin (x) = 3

Divide both sides by

2

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

Simplify

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

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

General solutions for

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

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

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

Combine all the solutions

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