i cant understand how can the plane is parallel to vector b and vector c .. can you draw me a better diagram. i cant imagine
The Attempt at a Solution
first if you take two lines that aren't parallel and that intersect at some point a then visually you should agree that there is palne that contains the two lines and the intersection point. right?
well vector b is along the first line and vector c is along the second line and a is the point in the plane.
