S17 Class 13: van der Pol Oscillator


Class 13:
Before class, watch the lecture material linked below and do the activity posted on Piazza.
Post at least one question or comment on Piazza (access via Canvas or directly).  See "Check Yourself" Q1 for details.
Check yourself via the Class 13 Check Yourself on Canvas (Due by 11:59pm on Tues Mar 7th)
In class, we'll work on related ideas: (activity will be posted)
After class, complete the homework (problems due Friday Mar 24th)
