Calcular un punto P de la recta que pasa por el Origen y tiene vector director V(1,3,4) cuya proyección en el plano z=0 es Q y tal que el triángulo formado por los tres puntos OPQ tenga área 1.

Es urgente su resolución, gracias.[/tex]

Hola Josan:

La ecuación de la recta es:

Si la recta debe pasar por el origen =>

=> x=t, y=3t, z=4t (ecuaciones 1)

Las coordenadas de cada punto son: P(t,3t,4t), Q(t,3t,0), O(0,0,0)

La altura del triangulo es z=4t La base del triángulo es OQ

El área del triángulo:



Calcular el valor de t y reemplazar en (ecuaciones 1) para hallar las coordenadas del punto P sobre la recta.

Saludos.
