What does a sine wave look like? In this video I look at how to graph and animate a sine wave in p5.js varying the period and phase. Code: thecodingtrain.com/tracks/the-nature-of-code-2/noc/3-angles/6-graphing-sine-wave

0:00 Good to see you again!
0:31 How do we graph a wave?
1:30 Let's do that right now!
3:18 Let's try varying the period
4:22 Why are we here again?
5:05 Change the starting angles
6:52 What happens if we go back to angular velocity?
7:19 Whoa! Let's use a static increment value
8:10 Go make something awesome!
9:29 See you in the next video!
