If The distance of point P(1,-2,1) from the plane x+2y-2z=k, where k>0, is 5, then what is the foot of the perpendicular from P to the plane ?
Find the line for perpendicular and do dot pro.
Are its easy....find the direction no.s of the perpendicular line...and its dot product withvthe directions no.s of the plane will b 0....u will gt d ans....
