tan(2x)=-(-270-120)/(130)

Solución

tan (2 x) = - \frac{- 270 - 120}{130}

x = \frac{1.24904 \dots}{2} + \frac{πn}{2}

radianes

x = \frac{1.24904 \dots}{2} + \frac{π}{2} n

Pasos de solución

tan (2 x) = - \frac{- 270 - 120}{130}

Simplificar

- \frac{- 270 - 120}{130} : 3

- \frac{- 270 - 120}{130}

Restar:

- 270 - 120 = - 390

= - \frac{- 390}{130}

Aplicar las propiedades de las fracciones:

\frac{- a}{b} = - \frac{a}{b}

= - (- \frac{390}{130})

Dividir:

\frac{390}{130} = 3

= - (- 3)

Aplicar la regla

- (- a) = a

= 3

Aplicar propiedades trigonométricas inversas

tan (2 x) = 3

Soluciones generales para

tan (2 x) = 3

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

2 x = arctan (3) + πn

2 x = arctan (3) + πn

Resolver

2 x = arctan (3) + πn : x = \frac{arctan ( 3 )}{2} + \frac{πn}{2}

2 x = arctan (3) + πn

Dividir ambos lados entre

2

2 x = arctan (3) + πn

Dividir ambos lados entre

2

\frac{2 x}{2} = \frac{arctan ( 3 )}{2} + \frac{πn}{2}

Simplificar

x = \frac{arctan ( 3 )}{2} + \frac{πn}{2}

x = \frac{arctan ( 3 )}{2} + \frac{πn}{2}

x = \frac{arctan ( 3 )}{2} + \frac{πn}{2}

3 tan (x + 4 3^{\circ}) = 2 cos (x + 4 3^{\circ})

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

4 sin (x) = 3 sec (x)

\frac{sin ( 55.01 - x )}{sin ( x )} = \frac{1200}{500}
