====== Lecture 27: Problem set 8 and solutions of the wave equation ====== This lecture follows along for {{ :ma20223:vectorpdes_problemsets_28jan2020.pdf |problem set 8}} and its {{ :ma20223:sol_ps08.pdf |solutions}}. We managed to get through Q1, Q3, and made a start on the (exhausting) Q4---or rather this was at the point I was exhausted (to pick up Q4 in another video!)
