Excellent, Dmitry! Can you explain why you make recordings for your students? Shouldn't your students make recordings for you?
This video is only one part of my video-dialog with students who, of course, do the same records for me with their questions. Normally I accompany these records with my explanations for a student too. SInce all explanations concern private problems I'm not sure that it's ok to publish them here, but I hope that my videos will be interesting for others.
