Trig Graph Project

This Fall our math department went to the Dallas Regional NCTM conference, and there was a pair of precalculus teachers discussing various projects they did. Great talk, and I took one of their projects and altered it to this:

I only wanted them to use ONE EACH of the 6 trig functions; they could restrict the domain; they were NOT supposed to restrict the range; they couldn't use any other functions; and then the were to color it. Here are some students that followed the directions.

    similar idea - asked them to make a small animal, using any of our families of functions (polynomials, lines, circles, exponentials, etc).

    Got a cool snail, a nice bird, a great shark, etc...

    I like that you are letting them create.


  2. That's cool. It's always enlightening to see the creativity in others' heads.

    Is this high school? or kindergarten? Where's the actual student thinking taking place?

  4. That looks like fun. What an engaging way to discuss the graphs of trig functions as well domain and range.
