Learn creative coding writing simple programs

67. Circular motion: sine and her cousin.

We have previously used sin() to generate numbers that continuosly slide between -1 and 1, but we did not study what sin() represented. This time we do that. We have a look at sine and cosine, two similar functions that help us create a circular motion. You can play with the sine/cosine tool at http://bit.ly/sine_cosine I hope it helps you understand sine and cosine.

To indicate that a word in your comment is code, use the `backtick`. Example
Do `float` and `int` smell similar?
 To highlight code blocks, surround it with ``` code-fences ``` like this:
``` void setup() { size(600, 600); } ```
