x = \frac{π}{4} + πn

Pasos de solución

sin (x) = sin (9 0^{\circ} - x)

Re-escribir usando identidades trigonométricas

sin (x) = sin (9 0^{\circ} - x)

Re-escribir usando identidades trigonométricas

sin (9 0^{\circ} - x)

Utilizar la identidad de diferencia de ángulos:

sin (s - t) = sin (s) cos (t) - cos (s) sin (t)

= sin (9 0^{\circ}) cos (x) - cos (9 0^{\circ}) sin (x)

Simplificar

sin (9 0^{\circ}) cos (x) - cos (9 0^{\circ}) sin (x) : cos (x)

sin (9 0^{\circ}) cos (x) - cos (9 0^{\circ}) sin (x)

sin (9 0^{\circ}) cos (x) = cos (x)

sin (9 0^{\circ}) cos (x)

Simplificar

sin (9 0^{\circ}) : 1

sin (9 0^{\circ})

Utilizar la siguiente identidad trivial:

sin (9 0^{\circ}) = 1

de ambos lados

sin (x) - cos (x) = 0

Re-escribir usando identidades trigonométricas

sin (x) - cos (x) = 0

Dividir ambos lados entre

cos (x), cos (x) \neq = 0

\frac{sin ( x ) - cos ( x )}{cos ( x )} = \frac{0}{cos ( x )}

Simplificar

\frac{sin ( x )}{cos ( x )} - 1 = 0

Utilizar la identidad trigonométrica básica:

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

tan (x) - 1 = 0

tan (x) - 1 = 0
