Pasos de solución

tan^{2} (x) = 5 sin^{2} (x)

Restar

5 sin^{2} (x)

de ambos lados

tan^{2} (x) - 5 sin^{2} (x) = 0

Factorizar

tan^{2} (x) - 5 sin^{2} (x) : (tan (x) + 5 sin (x)) (tan (x) - 5 sin (x))

tan^{2} (x) - 5 sin^{2} (x)

Reescribir

tan^{2} (x) - 5 sin^{2} (x)

como

tan^{2} (x) - (5 sin (x))^{2}

tan^{2} (x) - 5 sin^{2} (x)

Aplicar las leyes de los exponentes:

a = (a)^{2}

5 = (5)^{2}

= tan^{2} (x) - (5)^{2} sin^{2} (x)

Aplicar las leyes de los exponentes:

a^{m} b^{m} = (ab)^{m}

(5)^{2} sin^{2} (x) = (5 sin (x))^{2}

= tan^{2} (x) - (5 sin (x))^{2}

= tan^{2} (x) - (5 sin (x))^{2}

Aplicar la siguiente regla para binomios al cuadrado:

x^{2} - y^{2} = (x + y) (x - y)

tan^{2} (x) - (5 sin (x))^{2} = (tan (x) + 5 sin (x)) (tan (x) - 5 sin (x))

= (tan (x) + 5 sin (x)) (tan (x) - 5 sin (x))

(tan (x) + 5 sin (x)) (tan (x) - 5 sin (x)) = 0

Resolver cada parte por separado

tan (x) + 5 sin (x) = 0 or tan (x) - 5 sin (x) = 0

tan (x) + 5 sin (x) = 0 : x = 2 πn, x = π + 2 πn, x = arccos (- \frac{5}{5}) + 2 πn, x = - arccos (- \frac{5}{5}) + 2 πn

tan (x) + 5 sin (x) = 0

Expresar con seno, coseno

tan (x) + sin (x) 5

Utilizar la identidad trigonométrica básica:

tan (x) = \frac{sin ( x )}{cos ( x )}

= \frac{sin ( x )}{cos ( x )} + sin (x) 5

Simplificar

\frac{sin ( x )}{cos ( x )} + sin (x) 5 : \frac{sin ( x ) + 5 sin ( x ) cos ( x )}{cos ( x )}

\frac{sin ( x )}{cos ( x )} + sin (x) 5

Convertir a fracción:

5 sin (x) = \frac{sin ( x ) 5 cos ( x )}{cos ( x )}

= \frac{sin ( x )}{cos ( x )} + \frac{sin ( x ) 5 cos ( x )}{cos ( x )}

Ya que los denominadores son iguales, combinar las fracciones:

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

= \frac{sin ( x ) + sin ( x ) 5 cos ( x )}{cos ( x )}

= \frac{sin ( x ) + 5 sin ( x ) cos ( x )}{cos ( x )}

\frac{sin ( x ) + cos ( x ) sin ( x ) 5}{cos ( x )} = 0

\frac{f ( x )}{g ( x )} = 0 \Rightarrow f (x) = 0
