Graphs Explained
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.
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!
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.
