MA103: Multivariable Calculus

Unit 1: Vectors and Matrices   This unit begins with a discussion of vectors and vector algebra.  You will study and then be able to define the geometric properties of the dot product and the cross product.  You will learn vector algebra, which will allow you to perform operations on vectors themselves and not just their coordinates.  This will help you understand the geometric significance of the operations and computations performed.  You will then learn about parameterizations of lines and planes using vector algebra and geometry.  This way of thinking, i.e. going back and forth between algebra and geometry, will be very important for the rest of the course.  Finally, this unit introduces fundamental concepts of velocity and acceleration using vectors; this will allow us to study these concepts in their natural form.
