Objectives
-
To understand how to describe lines in space with parametric equations
-
To understand how the direction vector and base point are related to the geometric description of a line
Section 5.3 Lines in Space
Subsection 5.3.1 Lines in Space
This lesson focuses on correspondence between the information that is necessary to give the equation of a line and the geometric information needed to graph a line The parametric form of a line is motivated first using an example in two dimensions, then generalizing to an example in three dimensions. The description for how the parametric form of a line is animated in three dimensional example presented in this lesson. The playground on lines allows the user to move either of the two points used to define a line and the graph and equations are updated dynamically.
Subsection 5.3.2 Lines in Space Quiz
This quiz generates a random line and the user is asked several questions about the line presented.
