Why was iii a,b,c instead of f(a) ?

When looking at resolution and hoping to arrive at a []. Is it acceptable to arrive at [] early ? i.e. if i get there in 2 steps, do i need to continue or can i decide then that its not satisfiable because i was able to reach a [] ?]]>

Could anyone tell me if this is true? Can anyone tell me where I can get the $%*& thing! Trying to get any information of people supposedly working at Unisa is like - well, I would say pulling teeth but with pulling teeth at least when you feel the pain you know you're getting somewhere.

Also, if anyone can give me information like text books etc I would appreciate it, as I don't know when my registration will actually be processed (I have a loooooong history of administrative problems with Unisa).

Thanks

I'm a final year BSc student and I would like to know if Formal Logic 3 is compulsory for this module or recommended for this module.

If it is only recommended - in your opinion how much of help does it provide.

Planning to start honours in 2010 so I need to decide on my last module for next year.

Thank you]]>

Would anyone like to enlighten me?]]>

What do the bits above & below the lines mean after the first paragraph? It looks like division, but can't be (I think). How would one read those formulae/expressions? I did see the bit that says the bit above the line is called a premise and the bit below the line a conclusion but what does it mean? How do I use what is presented there?

The other bit that is confusing is: "The axioms are the sets of formulas containing a complimentary pair of literals". Which formulas? Any formula? Like can I start a proof of P -> Q with a, Ã¢Å’?a (even though a is not an atom in P or Q)?

I can follow the example proofs but, because of this lack of clarity, cannot see how I would begin one of my own. (Other than maybe to construct the tableaux for the formula's compilment and then write the proof down from that.

Any clarity at all would be most welcome.]]>

i need to choose an INF module that is straight forward, part theoretical part analytical, no research, no essay-type asignments/exam and one that doesn't have a very long syllabus.

any suggestions?]]>

I failed again :( I am askign for a remark though. I can't understand what I did wrong. Last year I got 32 %, this year, if I calculate my exam mark, I got 32% again. I was convinced I did a lot better this time round.]]>

I submitted Assignment 1 on the 12th February 2008. It was quite a strange assignment as due to the fact the Q1(iii) is not valid; it made answering some of the questions not as straight forward as it would have otherwise been.

Curveball...
