6 3
$$\frac{i \tan{\left(p \right)} \left(2 x - 16\right)}{6} = \frac{\sqrt{3}}{3}$$
Solución detallada
Tenemos la ecuación
$$\frac{i \tan{\left(p \right)} \left(2 x - 16\right)}{6} = \frac{\sqrt{3}}{3}$$
cambiamos
$$\frac{i \left(x - 8\right) \tan{\left(p \right)}}{3} - 1 - \frac{\sqrt{3}}{3} = 0$$
$$\frac{i \tan{\left(p \right)} \left(2 x - 16\right)}{6} - 1 - \frac{\sqrt{3}}{3} = 0$$
Sustituimos
$$w = \tan{\left(p \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\frac{i w \left(2 x - 16\right)}{6} - \frac{\sqrt{3}}{3} = 1$$
Dividamos ambos miembros de la ecuación en (-sqrt(3)/3 + i*w*(-16 + 2*x)/6)/w
Obtenemos la respuesta: w = -i*(3 + sqrt(3))/(-8 + x)
hacemos cambio inverso
$$\tan{\left(p \right)} = w$$
sustituimos w:
$$\frac{i \tan{\left(p \right)} \left(2 x - 16\right)}{6} = \frac{\sqrt{3}}{3}$$
cambiamos
$$\frac{i \left(x - 8\right) \tan{\left(p \right)}}{3} - 1 - \frac{\sqrt{3}}{3} = 0$$
$$\frac{i \tan{\left(p \right)} \left(2 x - 16\right)}{6} - 1 - \frac{\sqrt{3}}{3} = 0$$
Sustituimos
$$w = \tan{\left(p \right)}$$
Abrimos los paréntesis en el miembro izquierdo de la ecuación
-1 - sqrt3/3 + i*w2*x/6+16/6 = 0
Sumamos los términos semejantes en el miembro izquierdo de la ecuación:
-1 - sqrt(3)/3 + i*w*(-16 + 2*x)/6 = 0
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$\frac{i w \left(2 x - 16\right)}{6} - \frac{\sqrt{3}}{3} = 1$$
Dividamos ambos miembros de la ecuación en (-sqrt(3)/3 + i*w*(-16 + 2*x)/6)/w
w = 1 / ((-sqrt(3)/3 + i*w*(-16 + 2*x)/6)/w)
Obtenemos la respuesta: w = -i*(3 + sqrt(3))/(-8 + x)
hacemos cambio inverso
$$\tan{\left(p \right)} = w$$
sustituimos w:
