 Apr9 revised Why does closedness and boundedness for $S = \{ v \in V : || v||_{\infty} = 1\}$ imply that $S$ is compact in a finite dimensional vector space $V$? added 1 character in body Mar27 revised Why the column space of a matrix is useful? added 393 characters in body Mar26 revised Let $X$ be a topological space. Prove that for any $x$ in the intersection of all opens sets $=\{x \}$, the space $X$ need not be Hausdorff. edited body Mar19 revised Compact Projections to $S^1$ added 190 characters in body Mar12 revised what can you conclude about the number of solutions of the linear system Ax = b? added 98 characters in body Mar9 revised Measure of $E$ is the limit of the measure of the open set $\mathcal{O}_n$ added 5 characters in body Mar9 revised Measure of $E$ is the limit of the measure of the open set $\mathcal{O}_n$ added 483 characters in body Sep12 revised Why is differential geometry called differential geometry? [Edit removed during grace period] May13 revised Proving that there is no norm for the space of real-valued sequences making it a complete metric space. edited tags May13 revised Motivation of vector bundle of a manifold edited tags May11 revised Equivalent definitions of vector field added 84 characters in body Apr27 revised If $f$ is uniformly continuous on $\mathbb{R}$, $f(x) \ge a >0$ and $g(x) = 1/f(x)^2$, then $g(x)$ is uniformly continuous edited tags Apr11 revised Why do some series converge and others diverge? added 146 characters in body Apr11 revised Why do some series converge and others diverge? added 146 characters in body Apr10 revised How to use Hölder's inequality to show $L_q$ is a subspace of $L_p$? deleted 21 characters in body Apr10 revised Homotopy on the unit circle added 190 characters in body Dec6 revised Cardinalities of power sets, $\mathbb{N}$, and $\mathbb{R}$. tex edits Dec6 revised for any $A\subseteq X$, $f(\overline{A})\subseteq\overline{f(A)}$ , if and only if $f: X \to Y$ is continuous. tex edits Sep24 revised How to apply Borel-Cantelli Lemma here? edited tags Aug23 revised When is the logarithm of this function square integrable? edited title
