Check out my new course in Propositional Logic: trevtutor.com/p/master-discrete-mathematics-propositional-logic It comes with video lectures, text lectures, practice problems, solutions, and a practice final exam!
Mans dropped a banger after being in hiatus for six-months. Thanks, Trev. Your content is always top-quality, a free education punching above its own class.
AH, omg, the way I got excited when I saw you came back with a banger after 7 months!!! I honestly missed your videos and I need this so much. Saving our lives again, thanks king
hi trev, just wanted to let you know i love you :'D i was really hoping if you could cover calculus 3 as well, I'm taking it next semester and you're videos are so clear and concise and helpful, you're my go to when trying to learn math (you helped me so much in discrete and linear!) i would really appreciate it! hope you see this D:
Thank you so much for this, you really explained 6 lectures worth of material (with 20-30 slides per lecture) in time frame of a single lecture. Not only did you do this, but you did it in a way that was intuitive and really "clicked" with me. Again, thank you!
wow, the editing and clear instructions are just perfect! you have a talent for chopping up discrete math into easier bits for me to chew! thank you for taking the time to make this video !!! :)))
Are you going to make a similar video for Predicate logic? You're carrying the math of my Ai undergrad on your shoulders. I hope i can support you in the future. Thank you so much!
i learned so much about propositional logic and the terms again since I have forgotten it already!! these onclude conjunction, disjunction, biconditional, negation, and implication. this is also very uselful in real life applications! These examples really helped with my skills in reasons and validating arguments
Thank you very much! With this, I already feel more confident in passing the logic exam and not failing it again like the first time. Especially the inference rules make waay more sense now! Wish all profs explained matters like this! (And not with long-winded book explanations...)
18:06 I like it as if it were a promise. Whether you return and fulfill the promise or not, the statement is true. If you promise me and fulfill the promise, then the statement is true only if you keep your word.
I've been watching a number of your videos -- clear and excellent explanations, thank you. However, I have to object to your equating of the English "unless" to logical OR here and in another video. It is not the same. For example, let's consider the sentence "I'm going to the party, unless you are going to the same party". It can be rephrased without the use of "unless" as "If you are going to the party, I'm not going. If you are not going, I'm going." So, the truth table looks like this: 1 1 0 1 0 1 0 1 1 0 0 0 The original sentence can only be true if (and only if) only one of us is at the party. Both of us cannot be there (first line), because I said I'm not going if you are going. And none of us cannot be there (last line), because I said I'm going if you are not going. The truth table is different from OR's table, and is actually the same as XOR. What am I missing?
I have watched much of yours and others on formal logic but I keep coming across confusing terms: Do you mind helping me for predicate logic in explaining the difference between the following terms “interpretation” “structure” “semantics” “model” “theory”. Maybe visually also like if each fits inside another?
Trev,at 27:32 I get (0,0,1,0) for (p & ̴ q )because in my table I listed "q" first and "p" in the second column, so my final result became(1,0,1,0) ! The reason I thought that I must list q in the first column was that in the WFF we have (q→ ̴ p). Can you explain, what is the logical order of listing the variables in our table please? because then my result is q and not p!
This is going to sound pretty wild but what if for the implication table the last to options for p and q actually result in the answer 1 and 0 instead of 1. Effectively p and q are in a superposition until we know if we get desert or not 🎂.
