Hello.. I need help with vector equation!!!
Find the vector equation of the plane that passes through the points (1,2,7), (2,3,4) and (-1,2,1)
I know how to work out with the two pionts but not three
THANKYOU FOR HELPING ME = )
A plane can be defined as:
where is a point on the plane and is the normal vector.
Let points A, B, C be (1,2,7), (2,3,4) and (-1,2,1) respectively.
Notice that the plane contains vectors and and their cross product will give the normal vector perpendicular to it.
So find to get (a,b,c) and use one of A, B, or C for your .
Now, again, plug it all into:
