You're picking up the wrong $m+1$ there. Oct 15 comment Approximations other than taylor series and pade approximation Is there a specific reason for needing a function which approximates it as opposed to an iterative solver (e.g. Newton-Raphson)? Oct 15 comment Find value of '$t$' at a point on a cubic Bezier curve It's not at all clear what you're trying to do. Can you add a diagram?

Oct 14 revised Solutions to $x^3+y^3+z^3 = x^2 + y^2 + z^2=x+y+z=0$ All-Mathjax titles prevent people from right-clicking to open in new tab/window Oct 14 comment The pumping theorem and regular language The expression you pump can be simplified to $a^pbba^pbb$. Doesn't affect the argument, but making both $a^*$ use the same length might confuse people. Oct 12 reviewed Close Show that if $φ$ is an isomorphism, then $J$ is a non-zero constant. Oct 12 reviewed Close No. of positive eigen values of $3\times 3$ real matrix Oct 11 comment odds / percent is the game flawed or this seem accurate Note: 17% is probably rounded off from $\frac{1}{6}$. That might give you some insight into why it's alleged to have that win rate. Is it based around dice, perhaps? Oct 11 revised odds / percent is the game flawed or this seem accurate Formatting, no need for signature Oct 11 awarded Revival Oct 9 revised What is the difference between the terms 'equation' and 'algorithm'? This admits a definitive answer and hence is not a "soft question" Oct 9 comment “Where” exactly are complex numbers used “in the real world”? Computer graphics? I know that quaternions are used to represent and compose rotations, but what specific applications of complex numbers are there? (The others you mention could use specifics too: the question asks for applications, not fields having applications). Oct 8 revised Which complete graphs are (edge) magic? added 1 characters in body Oct 8 comment Which complete graphs are (edge) magic? It does work, and in fact it only takes the $4$ lexicographically first $4$-cycles. Thanks for the erratum, will correct. Oct 8 revised Which complete graphs are (edge) magic? added 46 characters in body Oct 8 comment Which complete graphs are (edge) magic? I'm working on a labelling for $K_5$ because I've realised that the reference I found misses it out entirely, but I can't see where the construction would break down. Oct 8 answered Which complete graphs are (edge) magic? Oct 8 comment Without Lagrange's theorem: If $H$ is a subgroup of odd order of $S_n$, then it is a subgroup of $A_n$. @MarshalKurosh, a permutation of odd parity applied an odd number of times gives a permutation of odd parity. Since the identity permutation has even parity, it follows that any permutation of odd parity has even order, whence every permutation of odd order is even and a member of $A_n$.
