Math

Tuesday will be our vector test. Let me just tell u guys something teacher didn say.

• A plane is a plane is a two-dimensional manifold or surface that is perfectly flat. Informally, it can be thought of as an infinitely vast and infinitesimally thin sheet oriented in some space. (wikipedia) This means that a place has no borders and it is 2D.


• Now I know why a(dot)n(unit vetor) = perpendicular distance from the origin. If anyone wants to know, u can always approach me in class.

These are a few facts that u might find useful.

Update people.
