Question

find the coordinates of the foot of perpendicular and perpendicular distance from the point P (4,3,2)0 the plane X + 2 Y + 3z is equals to 2 also find the image of P is the plane

Answer 1

You can find the direction ratio of the plane

And write it's general equation then the equation is (r.a).n=p

Where p is perpendicular distance from origin

a is a position vector in the plane

n is the position vector of the perpendicular
