Mar 13 answered Can $\frac {100-100}{100-100}=2$? Mar 13 asked Can a set containing a single vector from a vector space over a finite field be linearly dependent? Feb 20 answered How does this proof of the Cauchy-Schwarz Inequality work? Feb 18 answered Is -1 less than 0.1? Jan 18 asked Is the construction of $\mathbb{R}$ by Cauchy sequences due to Cauchy? For that matter, are Cauchy sequences due to Cauchy? Jan 9 answered Fixed point of tree automorphism Jan 9 answered Why is Euclid's proof on the infinitude of primes considered a proof? Dec 22 answered Why can $y-y_1 = m(x-x_1)$ describe a line but $m=(y-y_1)/(x-x_1)$ is missing a point? Dec 20 answered Wolfram Alpha unexpected answer. Dec 17 answered Question on Expected Value, discrete case Dec 17 answered Finding density function for uniform distribution Dec 17 asked “Let $G$ be a planar graph. Show that every pair of vertex-disjoint odd cycles in $G^c$ is connected by an edge.” Can't figure out why “odd” matters. Dec 16 answered Monty hall problem extended.
