midterm 1

Hi all,The first midterm will on my zoom room.  You need a camera and then I can monitor you online.The first midterm will be on May 2 (Sunday) 4:30- 5:30 pm. (Another 10 minutes to submit your solution) (California time). (Special time, not the lecture time)I choose this time, since I think it will work for most of you. If this really conflicts your schedule, please let me know.I will upload some practical question before the end of this week. And May 3 will have no lecture.
