Показать описание
In this lesson, we shall learn how to solve the vector equation, parametric equations and symmetric equations of a line in a 3d-plane.

In this lesson, we shall solve two examples...

For a line to be determine in a 3d-plane, it needs to have
1. a point the line passes through and a given direction, or
2. two points on the line where the line passes through

Usually, you shall be given
1. a point where the line passes through ie. Po(xo,yo,zo) and a vector that is parallel to line or
2. Two points the line passes through Po and P; for such cases, you need to find the vector PPo, and that becomes the vector parallel to the line and pass through the point Po.

At 9:24, how is a allowed to be 0, isn't that supposed to be undefined? Please clarify.
