Video Tutorial: Dynamic Function Switcher

I am finally getting to a lot of tutorial ideas that I've had built up for a while, so video tutorials are going to be coming out more often than once a week for a while. Today's tutorial is how you can great a graph that allows you to change between the graphs of the 6 trig ratios by using a slider. It uses indirection in a brand new way, so make sure you've seen my indirection tutorial first to understand what is going on. Please email your feedback to admin@lafacroft.com, as I would like to know if I am doing the video tutorials clearly, or if there is something that I could do to make them clearer and better.
