In the following case, determine whether the given planes are parallel or perpendicular, and in case they are neither, find the angles between them. 2x – 2y + 4z + 5 = 0 and 3x – 3y + 6z – 1 = 0
The distance of a point whose position vector is from the plane
The distance between two points P and Q is d and the length of the projections of PQ on the co-ordinate planes are d1, d2, d3. Then d21+d22 + d23 = kd2 where ‘k’ is
