I have a B.Sc in computer science and a B.Sc in mathematics from the Technion.

I am interested mainly in abstract algebra and I hope to start graduate school soon to continue study some advanced topics in this area.

Currently I am going over Abstract Algebra by Dummit and Foote to recall old topics and fill some gaps I have, while working full time as a programmer.

@YellowSkies - This is a very important theorem, you should at least learn its statement

comment 1. Given a group homomorphism $\psi: A_{8}\rightarrow S_{9}$ for which exists $\sigma\in A_{8}$ with $\psi(\sigma)=(12)$
an isomorphism to its image, not all of $G_2$ (this is practically the first isomorphism theorem applied to this case)

comment Distance of a point from a line
I don't understand, from "the dot product of two unitary vectors" I get that $A-M$ is a unit vector, why is that ? secondly, I don't understand why the said projection equals to the distance of $M$ from the line (did you mean $A$ ?, I would still not understand why, but $A$ makes more sense to me)

comment Checking irreducibility of $3x+6$ in $\mathbb Q[x]$ and $\mathbb Z[x]$
@patang - Herbert Quain answers add to mine. He gave you a factoring over $\mathbb{Z}$ and claimed it does not exist over $\mathbb{Q}$.

comment Equal integrals, circles, opposite directions
@Hagrid - This is part of the question that asks you to understand that going over this circle the other way around (i.e clockwise and not anti-clockwise) means that the integral value would be minus the value were we to go over the path the regular way

@Hagrid - Yes, you got it right!
