Week 8: Sinusoidal functions (cont.) plus...

Meetings were cancelled for three of the five groups last week, so we'll complete the activities with groups who haven't done so.

Then we'll try this problem. It's about developing a sinusoidal function to match a given graph. The answer is in the first comment below.

There were also 2 problems from the text that we didn't get to from Week 7, which should be suitable for some good, productive groupwork. Let's see how those work out.

Expect a 10-minute warm-up of questions to be solved using the unit circle.
