$$\tan{\left(t \right)} = \frac{x}{2}$$
Solución detallada
Tenemos la ecuación
$$\tan{\left(t \right)} = \frac{x}{2}$$
cambiamos
$$- \frac{x}{2} + \tan{\left(t \right)} - 1 = 0$$
$$- \frac{x}{2} + \tan{\left(t \right)} - 1 = 0$$
Sustituimos
$$w = \tan{\left(t \right)}$$
Transportamos los términos libres (sin w)
del miembro izquierdo al derecho, obtenemos:
$$w - \frac{x}{2} = 1$$
Move the summands with the other variables
del miembro izquierdo al derecho, obtenemos:
$$w = \frac{x}{2} + 1$$
Obtenemos la respuesta: w = 1 + x/2
hacemos cambio inverso
$$\tan{\left(t \right)} = w$$
sustituimos w:
