Your talent for teaching discrete math is a true gift to us all. You've made difficult concepts accessible for thousands, asking nothing in return. You've truly done your part in this world-thank you, you don't know how much I appreciate it :)

I've come this far in the playlist and I wanna say that your work environment of a small blackboard full of illustrative colors is very organized and easy to follow in a reassuring way. Thank you for this.

I'm struggling with this subject. Finding your video series is like finding fresh air after capsizing in a storm. This is incredibly helpful.

I really appreciate you going through the three different proof methods! I just started a discrete mathematics CS course and your videos are by far the best I've come across :)

você é realmente um anjo enviado pelos céus para me salvar, em 50 minutos de videos ensinou sobre tudo ( conjuntos na matematica discreta) que o meu professor demorou 1 trimestre para ensinar, e ainda por cima ensinou de um modo que eu consegui entender, vou salvar essa playlist para assistir ela inteira, ja estava desistindo de matematica de discreta na faculdade e deixando para ano que vem, porem depois de achar esses videos vou tentar passar com o conteudo dos videos, muito obrigado

Hey prof! Hope you're doing well. Just had a clarification. I get that we have to 'prove that if a set A is a subset of a set B and the set B is a subset of the set A, then A=B. It's perfectly logical. In the first proof of Demorgans 2nd law. We went from proving (A n B)' = A' U B' . Once we did that, we proved A' U B' = (A n B)' (Basically the vice versa). But WHY ? if LHS = RHS, doesn't is automatically imply that RHS=LHS ? The 2nd part of the proof seems redundant to me. Could you please explain it when you do have some time to spare ? Edit- it makes sense if you think about it as an implication i guess.. just because A implies B doesn't mean B implies A. so by doing the 2nd part of the proof, we are basically saying its a biconditional which makes sense to me.

We didn't prove that the left side equation equaled the right side. We proved that an element in one set is in the other set. Then we had to do the same in reverse to show that if any element is in one set, then it is in the other set.

Is there anyway for us internet people to get access to the homework?

Link to the solutions. It's not the homework, but can be somewhat useful I imagine! www.slader.com/textbook/9780073383095-discrete-mathematics-with-applications-7th-edition/
