| Mathematical Fundamentals |
Cartesian Co-ordinate System : In Cartesian co-ordinate system, we have, (u,v,w) = (x,y,z). A point P(x0, y0, z0) in Cartesian co-ordinate system is represented as intersection of three planes x = x0, y = y0 and z = z0. The unit vectors satisfies the following relation: |
