5+2tan(3θ+pi/3)=3

Solution

5 + 2 tan (3 θ + \frac{π}{3}) = 3

Solution

θ = \frac{πn}{3} + \frac{5 π}{36}

Degrees

θ = 2 5^{\circ} + 6 0^{\circ} n

Solution steps

5 + 2 tan (3 θ + \frac{π}{3}) = 3

Move

5

to the right side

5 + 2 tan (3 θ + \frac{π}{3}) = 3

Subtract

5

from both sides

5 + 2 tan (3 θ + \frac{π}{3}) - 5 = 3 - 5

Simplify

2 tan (3 θ + \frac{π}{3}) = - 2

2 tan (3 θ + \frac{π}{3}) = - 2

Divide both sides by

2

2 tan (3 θ + \frac{π}{3}) = - 2

Divide both sides by

2

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

Simplify

tan (3 θ + \frac{π}{3}) = - 1

tan (3 θ + \frac{π}{3}) = - 1

3 θ + \frac{π}{3} = \frac{3 π}{4} + πn

3 θ + \frac{π}{3} = \frac{3 π}{4} + πn

Solve

3 θ + \frac{π}{3} = \frac{3 π}{4} + πn : θ = \frac{πn}{3} + \frac{5 π}{36}

3 θ + \frac{π}{3} = \frac{3 π}{4} + πn

Move

\frac{π}{3}

to the right side

3 θ + \frac{π}{3} = \frac{3 π}{4} + πn

Subtract

\frac{π}{3}

from both sides

3 θ + \frac{π}{3} - \frac{π}{3} = \frac{3 π}{4} + πn - \frac{π}{3}

Simplify

3 θ + \frac{π}{3} - \frac{π}{3} = \frac{3 π}{4} + πn - \frac{π}{3}

Simplify

3 θ + \frac{π}{3} - \frac{π}{3} : 3 θ

3 θ + \frac{π}{3} - \frac{π}{3}

Add similar elements:

\frac{π}{3} - \frac{π}{3} = 0

= 3 θ

Simplify

\frac{3 π}{4} + πn - \frac{π}{3} : πn + \frac{5 π}{12}

\frac{3 π}{4} + πn - \frac{π}{3}

\frac{3 π}{4} = \frac{3 π 3}{4 \cdot 3} = \frac{9 π}{12}

= - \frac{π 4}{12} + \frac{9 π}{12}

Since the denominators are equal, combine the fractions:

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

= \frac{- π 4 + 9 π}{12}

Add similar elements:

- 4 π + 9 π = 5 π

= πn + \frac{5 π}{12}

3 θ = πn + \frac{5 π}{12}

3 θ = πn + \frac{5 π}{12}

3 θ = πn + \frac{5 π}{12}

Divide both sides by

3

3 θ = πn + \frac{5 π}{12}

Divide both sides by

3

\frac{3 θ}{3} = \frac{πn}{3} + \frac{\frac{5 π}{12}}{3}

Simplify

\frac{3 θ}{3} = \frac{πn}{3} + \frac{\frac{5 π}{12}}{3}

Simplify

\frac{3 θ}{3} : θ

\frac{3 θ}{3}

Divide the numbers:

\frac{3}{3} = 1

= θ

Simplify

\frac{πn}{3} + \frac{\frac{5 π}{12}}{3} : \frac{πn}{3} + \frac{5 π}{36}

\frac{πn}{3} + \frac{\frac{5 π}{12}}{3}

\frac{\frac{5 π}{12}}{3} = \frac{5 π}{36}

\frac{\frac{5 π}{12}}{3}

Apply the fraction rule:

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

= \frac{5 π}{12 \cdot 3}

Multiply the numbers:

12 \cdot 3 = 36

= \frac{5 π}{36}

= \frac{πn}{3} + \frac{5 π}{36}

θ = \frac{πn}{3} + \frac{5 π}{36}

θ = \frac{πn}{3} + \frac{5 π}{36}

θ = \frac{πn}{3} + \frac{5 π}{36}

θ = \frac{πn}{3} + \frac{5 π}{36}
