yeah that's a common issue, the best way is to show every single step and justify every single step, make it as detailed as possible. A common thing is, you get your test back, and you lose points because you thought a certain part was obvious, but it wasn't. Anyways yeah, I know what you mean!
Thanks A LOT! I've been struggling with this problem which shows up on Ch. 1 of Zorich's Analysis I Book. Actually the problem is to prove that if B X D ≠ Ø then the relation is two-ways (iff), but I think that part is left to me as an exercise :p Keep up the great work Sir.
When I read the word 'sorceror' it already reminded me of my fav Harry Potter series....and when I saw you...OMG...u wear the hat which actually looks like the one which classified students to Slytherin, Gryffindor and other grps! This was really very surprising!
it is not! I actually made a video for you and was going to post it! BUT, someone on the forums gave a really good answer to your question, so check it out. I am assuming you asked on mathsorcererforums.com, so check the reply there. Good question:)
@@TheMathSorcerer thank you so much for your help and for making great/informative vids. I am trying to teach myself Set Theory by using Munkres Topology (first chapter) and Schaums Outline which I find to be a great source of examples. Problem is Munkres doesn't offer any solutions so sometimes I don't know if I'm on the right track (exercise 2, problem K, L). Seems to me that he is asking to analyze different cases/scenarios when either set A or B is empty. The non empty case I did without any problems.
wtf why is a random youtuber dressed as a wizard better at teaching proofs than my professors that earns a six figure salary
and also free
some of these things are obvious but I'm never sure about how detailed the proof must be in order to be taken as correct (for example in a test)

Nice proof! Question: is the converse true?
it is not! I actually made a video for you and was going to post it! BUT, someone on the forums gave a really good answer to your question, so check it out. I am assuming you asked on mathsorcererforums.com, so check the reply there. Good question:)
