Find an equation of a plane that is perpendicular to the plane x-2y+z=7
I know his has to do with vectors because the dot product must = 0....
There is an infinite number of answers . . .Find an equation of a plane that is perpendicular to the plane
A door is perpendicular to the floor. .Swing the door
. . and you have thousands of planes perpendicular to the floor.
Our plane can go through any point, say,
Its normal vector, , must be perpendicular to
Hence, we have: .
. . We can use, for example: .
The equation is: .
