Sticks and Shadows

What's the connection between circles and triangles? That's what we've been talking about in class.

Trigonometry has something to do with it. I found an excellent site that allows you to play and learn all about it. Start with Stick and Shadows Part I and play through to Frequency and Amplitude.

Tomorrow we're going to talk about how to graph the sine, cosine and tangent functions. You can do a little preview here.

If you review this material before our class tomorrow you'll find class really easy to follow.

And, finally, as promised, the answers to Exercise 4 (page 1 of 2, page 2 of 2) and Exercise 5 (page 1 of 2, page 2 of 2).
