Find equation of the plane parallel to x + 3y – 2z + 7 = 0 and passing through the origin.
In each of the following cases, determine the direction cosines of the normal to the plane and the distance from the origin.
z = 2
The equation of plane is
z = 2 or 0x + 0y + 1.z = 2
It is of form lx + my + nz = p
where l = 0, m = 0, n = 1, p = 2
∴ direction cosines of the normal to the plane are 0, 0, 1 and distance from origin = 2.
In each of the following cases, determine the direction cosines of the normal to the plane and the distance from the origin.
x + y + z = 1
