Basic Transformations of Graphs: Translations
Given a sketch of y = f(x), does y = f(x-3) then correspond to a shift to the left or to the right of that graph? Here's how to deal with such basic graph transformations with ease.
The Graph of an Inverse Function is a Reflection
Why is the graph of an inverse function just a reflection of the graph of the original function about the diagonal line y = x? The answer is social convention - not mathematics! In this video I explain!
Graphing Complex Numbers
In this video we give a very brief description of the mechanics to plotting complex numbers on a plane. Sounds dreary, but the motivation I offer that leads up to it is not! That's the interesting part.
