Not bad! Let's hope all the other ones will look like this tomorrow. I'll be verrrrry happy. They're also supposed to turn in a 3-D form of this, whereby they draw their curve on poster board, cut it out, and glue the two ends (leftmost x and rightmost x) together to form a sort of loop. That's why their leftmost and rightmost function and derivative values also need to match up. And they need to turn in either calculation work leading up to the equations, or an explanation of how they did it.
Hurray to the end of an era. Next week, we will start another project!
