i really have not idea about this one,

i try to deal with, but it is not correct.

what's problem

Another approach to nding the line of intersection of the two planes x+6y+2z=1 0 4 0 x: 1 +1 3 +p 3 0 0 4 is to rst convert both into Cartesian form, and then solve the system of two equations. all '3 and the co-ordinate vector for a point on the plane is p = (xp).n=0. and Since a normal vector to the second equation is n = 9'\" we can write the second plane in point-normal form: Note: the Maple syntax for a vector is . From this we can determine that the intersection of the two planes is a line which is parallel to the vector and where a is the oo-ordinate vector for a point on the line. 9' Note: use the Maple syntax for a vector for both these answers, e.g.
