Grados

x = 43.87975 \dots^{\circ} + 36 0^{\circ} n, x = 136.12024 \dots^{\circ} + 36 0^{\circ} n

Pasos de solución

7 = e^{2 s i n (x)} + 3

Intercambiar lados

e^{2 s i n (x)} + 3 = 7

Mover

3

al lado derecho

e^{2 s i n (x)} + 3 = 7

Restar

3

de ambos lados

e^{2 s i n (x)} + 3 - 3 = 7 - 3

Simplificar

e^{2 s i n (x)} = 4

e^{2 s i n (x)} = 4

Aplicar las leyes de los exponentes

e^{2 s i n (x)} = 4

Si

f (x) = g (x)

, entonces

ln (f (x)) = ln (g (x))

ln (e^{2 s i n (x)}) = ln (4)

Aplicar las propiedades de los logaritmos:

ln (e^{a}) = a

ln (e^{2 s i n (x)}) = 2 sin (x)

2 sin (x) = ln (4)

2 sin (x) = ln (4)

Resolver

2 sin (x) = ln (4) : sin (x) = ln (2)

2 sin (x) = ln (4)

Dividir ambos lados entre

2

2 sin (x) = ln (4)

Dividir ambos lados entre

2

\frac{2 sin ( x )}{2} = \frac{ln ( 4 )}{2}

Simplificar

\frac{2 sin ( x )}{2} = \frac{ln ( 4 )}{2}

Simplificar

\frac{2 sin ( x )}{2} : sin (x)

\frac{2 sin ( x )}{2}

Dividir:

\frac{2}{2} = 1

= sin (x)

Simplificar

\frac{ln ( 4 )}{2} : ln (2)

\frac{ln ( 4 )}{2}

Simplificar

ln (4) : 2 ln (2)

ln (4)

Reescribir

4

utilizando potencias:

4 = 2^{2}

= ln (2^{2})

Aplicar las propiedades de los logaritmos:

lo g_{a} (x^{b}) = b \cdot lo g_{a} (x)

ln (2^{2}) = 2 ln (2)

= 2 ln (2)

= \frac{2 ln ( 2 )}{2}

Dividir:

\frac{2}{2} = 1

= ln (2)

sin (x) = ln (2)

sin (x) = ln (2)

sin (x) = ln (2)

sin (x) = ln (2)

Aplicar propiedades trigonométricas inversas

sin (x) = ln (2)

Soluciones generales para

sin (x) = ln (2)

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

x = arcsin (ln (2)) + 2 πn, x = π - arcsin (ln (2)) + 2 πn

x = arcsin (ln (2)) + 2 πn, x = π - arcsin (ln (2)) + 2 πn
