  1. In Topic: -0 paradox

    20 May 2012 - 02:02 AM

    Quote

    If you divide a number by 0 your answer would be infinity. So if you divided a number by -0 you must have an answer of -infinity.


    Dividing by zero is not defined.

    Quote

    Is 0 a paradox or is it infinity and an infinitesimal at the same time?



    If you are asking the mathematical question what is zero, and looking at the rational or real numbers as fields -- i.e.: a place where you can add, multiple, have multiplicative and additive inverse, have additive and multiplicative identities, and other "natural" properties -- then 0 is simply the additive identity. If you are asking the philosophical question whether zero exists, then I don't think mathematics really has an answer for you, other than the fact that many mathematical objects have nice properties if we assume they have a "zero".

  2. In Topic: Lab Accidents

    12 May 2012 - 03:26 AM

    Not as exciting as some of the chemistry accidents, but the commons in the math department recently got a glass wall with fancy frosted glass intended to be used as a dry erase board. Well, one side of the glass was a dry erase board if you wrote on the frosted side it is apparently permanent. So now the commons has a fancy glass mural depicting the struggle of students working with Mayer-Vietoris and the Snake Lemma.

  3. In Topic: Mean Value Problem

    17 January 2012 - 12:26 AM

    Sorry I was sloppy when I stated what I had done towards a solution:

    I did get that
    f(0)-2f(1)+f(2)=-f'(a)+f'(b)=f''©(b-a).


    where c is in [0, 2]. But the there is still the (b-a) term that needs to be taken care of somehow, and that is where I was stuck. Sorry for the poor description in the OP.

  4. In Topic: Guide to a Mathematics Course

    24 December 2011 - 12:28 AM

    As people have previously said, it really depends on what you courses you are taking, and what area of mathematics you plan on studying, and your mathematical maturity. If you are planning on majoring in "pure" maths then at some point you will need to begin taking rigorous proof based courses. If you have little experience to proofs and theoretical mathematics you might want to consider a intro to proofs book such as "How to Prove It" by Daniel Velleman or "Mathematical Proofs" by Gary Chartrand. Although to be honest the best way to learn "how to do proofs" is by doing them yourself.

    As has been said if you have already taken basic calculus, i.e.: single variable, you may want to consider reading up on introductory real analysis. Personally, I really like Spivak's Calculus or little Rubin for this. However, these books are more expensive than the one Dr. Rocket recommended.

    The course i'll make starts with Linear Algebra.


    If you are looking for a good complete Linear Algebra book I would recommend Hoffam and Kunze's Linear Algebra. Although be forewarned that this book is a fairly theoretical approach, and so if you are new to theoretical mathematics you might want to use a book that is a little more concrete.


  5. In Topic: Cardinality of Real Numbers Paradox?

    Can this be proven? And if so, can you give me an outline of this, or a general direction to look into?


    Prove that .999...=1 and then generalize your argument.

    Right now we're kind of putting GUTs on hold. I'll get back to you when we've sorted everything out.
