Test #3 topics + Webwork hints

I wrote the wrong sections for Test #3 on the board today. As announced many times throughout the semester, Test #3 covers the green sections on the schedule, so Sections 13-20.

For the Webwork questions where you are manipulating a graph to match the formula of the function, determine the amplitude, phase shift, and period first. When you’re dragging points, if you change the phase shift, it might alter your period (especially if you’re trying to do this on a phone instead of a computer) so change the phase shift first, then your period.

For the Webwork questions where you are given graphs and entering formulas, click on the picture of the graph to enlarge it. You’ll be better able to see the scale on the x-axis this way.
