Hi, my name is Zack. I work IT in the USAF and am a part-time CS instructor at a community college. I am finishing my last masters course this month in Computer Science.

As a computer science instructor, I recommend Java as your first object oriented language for learning. The reason most colleges and universities use Java as the language of choice for 'Intro to Programming' courses is because of it's simplicity. Once you grasp the basics of Java, then you can search for a better language for your modeling needs.

I kicked myself after thinking deeper about entailment. This whole time I've been trying to prove equivelancy between two equations when I really needed to just prove which one was always true when the first is true. I plugged all the equatinos into Excel and changed the values of A, B, C, D, and E and everytime the problem was true, #2 was also true. I did this a few days ago but got frustrated because I was thinking that when the first is false the others needed to be false also...which is not entailment. Thanks for all the help!

"can be logically inferred"

My reasoning was simple. #2 was the only choice with variables A, B, C, D, and E and there is nothing as far as I can see that would cancel out a variable.

I keep going in circles trying to figure out the answer. Please help! 2. makes the most sense to me, but I am not sure what to do with the part with the --> Which of the following are entailed by the sentence (A V B) Λ (¬C V ¬D V E)? (A V B) (A V B V C) Λ (B Λ C Λ D --> E) (A V B) Λ (¬D V E) ! Moderator Note Identical threads merged
