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 ...
