## Course Description

In this course, we begin with an introduction to vectors. We discuss vectors in the plane, and we go into detail on vector addition, scalar multiplication, and the length of a vector. Many properties of vectors and unit vectors are also covered.

After this introduction to vectors, we begin working in three dimensions. Many of the concepts just introduced are implemented easily in 3-space. We describe the dot product and cross product, including vector projections, work, and finding areas. Many properties of both these operations are covered in detail with several examples.

After these studies on vectors, we discuss lines and planes in space. We thoroughly explain equations of lines in space, equations of planes in space, and several other topics such as the angle between two planes and the distance between a point and a plane.

After studying vectors, lines, and planes, we now investigate surfaces in space. We cover cylinders and various types of quadratic surfaces, including ellipsoids, hyperboloids, cones, and paraboloids.

Having explored rectangular coordinates so far in this course, we now turn our attention to other coordinate systems. The cylindrical coordinate system and the spherical coordinate system are detailed. We explain how these coordinate systems work and how to convert points and equations between them, including rectangular coordinates.
