I have 3 points A,B and C, with coordinates (0,1,1) (-2,-1,-5) and (1,-1,0)
I have found vectors AB and AC, the found the equation of the plane ABC as
r= (0,1,1) + λ(-2,-2,-6) + μ(1,-2,-1). the brackets in the 'r=' formula are vertical brackets. I am having trouble verifying that A,B and C lie in the plane
5x + 4y - 3z = 1

. . . Really?
If a point lies in a plane, its coordinates satisfy the equation of the plane.
. . . . . basic stuff!
It's like asking: How do I know thatis on
?
thanx for pointing that out for me, my brain wasn't fully switched on
