1) may be written a b c i.e., - + ^ + - = 1; [73] a b c and this is the equation of the plane in terms of its intercepts. From equations (2) it is clear also that the intercepts of plane (1) are a = --, b = --, c=--. (3) 148. The normal equation of a plane. A plane is whollydetermined in position… … equation. Let OQ bethe perpendicular fromthe origin 0 to theplane ABC, let p be itslength, and let a, p, ybe its direction angles.Let P = (x, y, z) be anypoint of the plane (otherthan Q), and draw itscoordinates OM, MM,and MP. Then, projecting upon OQ, proj. OJf+proj. MM + -pTo]. JlfP=proj. OP,that…
