Sorry if this is the wrong subthread. I am a selftaught programmer, and have been learning discrete math (for algorithms) from a text book: Discrete Mathematics and its Applications, 6th edition. I usually don't have trouble with the material, but there is a particular question in the chapter on logic: "32. show that the equivalence pâˆ§Â¬pâ‰¡F can be derived using resolution together with the fact that a conditional statement with a false hypothesis is true [Hint: let q = r = F in resolution.]" I am totally lost, what am I supposed to do here?

Would this also work for an appropriate answer: q = r = F; (pâˆ¨q) âˆ§(Â¬pâˆ¨r) â‰¡ (Â¬pâ‡’q) âˆ§(pâ‡’r) â‰¡ Tâˆ§F â‰¡pâˆ§Â¬pâ‰¡F
