Solución

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

Solución

x = πn, x = arcsin (a) + 2 πn, x = π + arcsin (- a) + 2 πn, x = arcsin (- a) + 2 πn, x = π + arcsin (a) + 2 πn, x = arcsec (a) + 2 πn, x = - arcsec (a) + 2 πn

Pasos de solución

x = 0 + πn

x = 0 + πn

Resolver

x = 0 + πn : x = πn

x = 0 + πn

0 + πn = πn

x = πn

x = πn

sin^{2} (x) - a = 0 : x = arcsin (a) + 2 πn, x = π + arcsin (- a) + 2 πn, x = arcsin (- a) + 2 πn, x = π + arcsin (a) + 2 πn

sin^{2} (x) - a = 0

Usando el método de sustitución

sin^{2} (x) - a = 0

Sea:

sin (x) = u

u^{2} - a = 0

u^{2} - a = 0 : u = a, u = - a

u^{2} - a = 0

Mover

a

al lado derecho

u^{2} - a = 0

Sumar

a

a ambos lados

u^{2} - a + a = 0 + a

Simplificar

u^{2} = a

u^{2} = a

Para

x^{2} = f (a)

las soluciones son

x = f (a), - f (a)

u = a, u = - a

Sustituir en la ecuación

u = sin (x)

sin (x) = a, sin (x) = - a

sin (x) = a, sin (x) = - a

sin (x) = a : x = arcsin (a) + 2 πn, x = π + arcsin (- a) + 2 πn

sin (x) = a
