Oscillation starts with sine and then uses cosine

Oscillation amplitude and period section starts with a graph of sine. It then uses cosine in the text and in the example code. However, it feels like it's referring to sine (it says it starts at 0, which is what sine does). I am changing it to sine in the Khan port.

Thanks, I'll update the book to do the same.
