Intersections of Lines & Planes How do I tell if a line is parallel to a plane? A line is parallel to a plane if its?direction vector?is?perpendicular?to the plane’s?normal vector If you know t...
Equation of a Plane in Vector Form How do I find the vector equation of a plane? A plane is a flat surface which is two-dimensional Imagine a flat piece of paper that continues on forever in both d...
Shortest Distance between a Point & a Line How do I find the shortest distance from a point to a line? The shortest distance from any point to a line will always be the?perpendicular?distance G...
Scalar Product The?scalar?product?is an important link between the algebra of vectors and the trigonometry of vectors. We shall see that the scalar product is somewhat comparable to the operation o...
Coincident & Parallel Lines How do I tell if two lines are parallel? Two lines are parallel if, and only if, their?direction vectors?are?parallel This means the direction vectors will be?scalar...
Equation of a Line in Vector Form How do I find the vector equation of a line? You need to know: The?position vector?of one point on the line A?direction vector?of the line (or the position vector ...
