    Count & Describe Automorphisms of Z_3 (Set of Integers Modulo 3)

    Okay well, I figured it out. Alpha was defined a few pages earlier as a root of x^2+1 (a polynomial with coeff's in Z_3[x]). Thanks for pointing out what should have been obvious to me.

    Count & Describe Automorphisms of Z_3 (Set of Integers Modulo 3)

    Please bear with me as I don't have latex. This is a homework question I have and I don't even know if it makes sense: How many Z_3 (set of integers modulo 3) vector space automorphisms of Z_3(alpha) are there? Describe them. I'm not sure if alpha is supposed to be the root of some...

    Notation of ideals in ring theory

    Nevermind, I figured it out. Thanks for the insight Ziox!

    Notation of ideals in ring theory

    Okay well, it turned out that the idea from wolfram was more confusing than helpful. There's a scarce amount of information in my text and notes on PID's. The only conjectures that I feel safe in making: if given gcd(a,b)=d then gcd(a,d)=d and gcd(b,d)=d. Not sure how helpful those are though. I...

    Notation of ideals in ring theory

    So right now I'm trying to solve this problem in ring theory for homework. The question pertains to proving that in a PID, D, if a,b are elements of D then the gcd of a and b can be written as a linear combination. In any event I know where I have to go but I'm stuck on this one bit of notation...

    Chemistry Career in Chemistry: Level of Difficulty?

    Hey guys, Right now I'm on my way to getting my bachelor's in mathematics. However, I've recently considered double majoring in chemistry as well. Could anyone attest to the level of difficulty in a chemistry major? Is it comparable to a mathematics major or less? Thanks in advance!

    Images under exp in complex plane

    Here exp is notation for euler's number in the complex plane.

    Images under exp in complex plane

    Describe the image under exp of the line with equation y = x. To do this you should find an equation (at least parametrically) for the image (you can start with the parametric form x = t; y = t), plot it reasonably carefully, and explain what happens in the limits as t approaches infinity and t...

    Bad Modern Algebra Book, but good choice

    I went into this semester ignoring many remarks that Modern Alg. is a very hard course. I think the course material was a difficult at times but certainly not impossible. Like all math courses it required time and patience. However, I have had a rude awakening. I have never had such a course...

    Courses What is the highest level of math courses available?

    I'll just list a couple courses for applied mathematics: Calculus 1- Calculus 3 Linear Algebra Differential Equations Probability and Statistics Partial Differential Equations Advanced Linear Algebra Real Analysis It's not an exhaustive list but it hits the more common math courses for...

    Schools Necessary classes before graduate school

    Yeah, I definitely would not bother with abstract algebra, unless your a masochist :tongue2:

    Is a career in mathematics the key to success in intelligence agencies?

    That's a question I've often asked myself... heh :tongue2: just kidding. But yeah, it does sound pretty interesting. As a gov position it's quite likely you could continue in school at taxpayers expense and possibly work into other departments - where ever your interests are... (spy, spy...

    What do you guys think about this? Sound like a desk job or an awesome opportunity? http://www.cia.gov/employment/jobs/science_tech_weapons_analyst.html
