It’s Time To Think Rationally

This screencast is all about rational functions, where one polynomial divides another. It’s a fairly complicated process to sketch them, given all the asymptotes that show up when the denominator approaches zero. However, if you sit through this slightly longer than usual video, I show off my new toy: FluidMath! I’m planning on writing a post soon that displays more of its features, but I’m still learning the basics of it. I haven’t been this excited and impressed about math-related software since many years ago when I first saw Geometer’s Sketchpad on a Mac Classic.
