 Apr 3 accepted Commutativity of multiplication of cosets of the commutator subgroup Apr 3 asked Commutativity of multiplication of cosets of the commutator subgroup Apr 2 comment show the form of a subgroup when the index and order are relatively prime Such a subgroup is called a "Hall subgroup", by the way. Nov 13 comment Find root of $x^2 + bx + c$ with an approximation for $b$ Yeah, $x$ is also an integer. Forgot to mention that, sorry.

Nov 13 asked Find root of $x^2 + bx + c$ with an approximation for $b$ Nov 2 accepted Number of dice rolls taken to reach a certain sum Oct 24 comment Show linear independence of cosines I think eigenvalues as a tool are out of scope, since we haven't covered them in the course. Thank you though. I like your book a lot. Oct 24 accepted Show linear independence of cosines Oct 24 comment Show linear independence of cosines I agree, this is very elegant. Much more elegant than the solution I ended up putting on the exam, heh. Oct 24 comment Show that $\{cos(cx) | c \in \Bbb{R}, c > 0\}$ is a linearly independent subset of $W$. I definitely know where this question came from, heh. How'd you do on the test?

Thank you very much. I don't quite understand the second step, where you pull the (t-k) out - can you explain that?
