In order that
point from the origin to a point on
it is enough that the components of satisfy the equation that defines the plane: that is, that
need guidance to solve my vector problem here.. =)
Let Rd = (a)i + (6)j + (1)k be the position vector of point D.
Determine the value of a so that D lies in the plane ABC
ABC plane => x + 6y -8z = 5
