Spring is a great season for symmetry. Flowers have mirror and rotational
symmetry. Day lengths building up to the summer solstice are approximately
symmetric to those that follow. On the first day of spring a plane through the
equator splits the sun into two symmetric halves.
So it is that the Friday Fave is thinking about symmetry on this fine spring day in the northern hemisphere. (Sorry, Australia!)
This isn’t a high-production super-ambitious sort of thing. Its mission is simple—to give students a chance to train their eyes for two kinds of symmetry of functions.
And then it ends with a killer extension.
Simple set up; powerful thinking. That makes Symmetry a Friday Fave.
While you’re thinking about transforming functions, here are a few on that theme:
