Dear Staff , As usual I prefer hints and explanations on the way to approach the answer.
Consider the plane (P) of equation : x - 2y + 3z + 1 = 0.
1- Find two normal vectors to (P).
My Answer ; N1 ( 1 , -2 , 3 ) N2 ( -1 , 2 , -3)
2- Determine three points A , B and C on (P) .
3- Is the point I( 1 , -2 , 3 ) on (P) .
Thanks in advance ,
