Course: Calculus III
Topic: Vectors and Geometry of Space
Subtopic: Lines and Curves


The wonders of three dimensional objects! Expanding lines and curves from 2D to 3D, describing and analyzing curves in 3D, studying special 3D curves such as the helix. Merging vectors, functions, and parametric equations into vector-valued function used to track points in space as they spin out curves. These are among the visually exciting things this section brings.


By the end of this topic you should know and be prepared to be tested on:


Define: orientation of a curve, helix curve, roller coaster curve, slinky curve

Formulae to have in your notes: equation of a line (vector, symmetric, and parametric forms); equation of line segment
