Calculus III - Equations of Lines. In this section we need to take a look at the equation of a line in .
As we saw in the previous section the equation. Determine if points are in a straight line? The Equation of a Line in 3-Space.mp4. Lines and planes in 3 dimensions. Plane through a Point and containing a Line. Angles between lines and planes. In this section we'll look at how to find the angle between 2 lines the angle between 2 planes the angle between a line and a plane.
Each of these will involve calculating the size of an angle between 2 vectors. How to do this is explained near the end of the dot product section. Now all we need to do is to decide which 2 vectors we need to work with in each case. The angle between 2 lines.
