tan(3φ-4)=-1/2 ,0<= φ<= pi/2

tan (3 φ - 4) = - \frac{1}{2}, 0 \leq φ \leq \frac{π}{2}

φ = \frac{- 0.46364 \dots + 4}{3}, φ = \frac{- 0.46364 \dots - π + 4}{3}

Degrees

φ = 67.53935 \dots^{\circ}, φ = 7.53935 \dots^{\circ}

Solution steps

tan (3 φ - 4) = - \frac{1}{2}, 0 \leq φ \leq \frac{π}{2}

Apply trig inverse properties

tan (3 φ - 4) = - \frac{1}{2}

General solutions for

tan (3 φ - 4) = - \frac{1}{2}

tan (x) = - a \Rightarrow x = arctan (- a) + πn

3 φ - 4 = arctan (- \frac{1}{2}) + πn

3 φ - 4 = arctan (- \frac{1}{2}) + πn

Solve

3 φ - 4 = arctan (- \frac{1}{2}) + πn : φ = - \frac{arctan ( \frac{1}{2} )}{3} + \frac{πn}{3} + \frac{4}{3}

3 φ - 4 = arctan (- \frac{1}{2}) + πn

Simplify

arctan (- \frac{1}{2}) + πn : - arctan (\frac{1}{2}) + πn

arctan (- \frac{1}{2}) + πn

Use the following property:

arctan (- x) = - arctan (x)

arctan (- \frac{1}{2}) = - arctan (\frac{1}{2})

= - arctan (\frac{1}{2}) + πn

3 φ - 4 = - arctan (\frac{1}{2}) + πn

Move

4

to the right side

3 φ - 4 = - arctan (\frac{1}{2}) + πn

Add

4

to both sides

3 φ - 4 + 4 = - arctan (\frac{1}{2}) + πn + 4

Simplify

3 φ = - arctan (\frac{1}{2}) + πn + 4

3 φ = - arctan (\frac{1}{2}) + πn + 4

Divide both sides by

3

3 φ = - arctan (\frac{1}{2}) + πn + 4

Divide both sides by

3

\frac{3 φ}{3} = - \frac{arctan ( \frac{1}{2} )}{3} + \frac{πn}{3} + \frac{4}{3}

Simplify

φ = - \frac{arctan ( \frac{1}{2} )}{3} + \frac{πn}{3} + \frac{4}{3}

φ = - \frac{arctan ( \frac{1}{2} )}{3} + \frac{πn}{3} + \frac{4}{3}

φ = - \frac{arctan ( \frac{1}{2} )}{3} + \frac{πn}{3} + \frac{4}{3}

Solutions for the range

0 \leq φ \leq \frac{π}{2}

φ = \frac{- arctan ( \frac{1}{2} ) + 4}{3}, φ = \frac{- arctan ( \frac{1}{2} ) - π + 4}{3}

Show solutions in decimal form

φ = \frac{- 0.46364 \dots + 4}{3}, φ = \frac{- 0.46364 \dots - π + 4}{3}

g, θ = arctan (\frac{5.54}{10 g} + 0.2)

tan (t) = \frac{3}{4}

2 cos (θ) - 2 sin (2 θ) = 0

tan (x) = \frac{5}{3} sin (x) [0.2 π]

4 sin^{2} (x) - cos^{2} (x) = 0
