 Apr8 comment Riddle: 1 question to know if the number is 1, 2 or 3 Since the girl knows EVERYTHING about number 1, she knows if the boy is thinking to that number... Apr7 awarded Necromancer Apr6 asked Nice application of fixed point theorems Mar14 answered Help understanding the proof for the infinity case of L' Hopital's Rule. Mar14 revised Prove that $n^2$ tends to infinity as $n$ tends to infinity added 6 characters in body Mar14 answered A 'different' explanation to “Supremum” Mar14 answered Prove that $n^2$ tends to infinity as $n$ tends to infinity Feb18 comment Uniform convergence and bounded increasing function. Take the functions $f_n(x) = |\sin n| x$. These are increasing functions which do not converge as $n\to \infty$. Feb15 revised Proving that lines from any vertex of a parallelogram to the midpoints of the opposite sides trisect a diagonal added 64 characters in body Feb15 answered Proving that lines from any vertex of a parallelogram to the midpoints of the opposite sides trisect a diagonal Feb14 answered Proof that the $\lim\limits_{x \to 2}\dfrac{1}{x} = \dfrac{1}{2}$ using the $\epsilon$-$\delta$ definition of limits (verification). Feb7 revised Can we define the concept of limit without a topology? translation Feb7 answered Question about non conservative vector field Feb7 comment Question about non conservative vector field They don't speak at all... so they are not conversative Feb5 answered Prove that $\ln x$ is not uniformly continuous on $(0,1]$ Feb3 comment Is $f(x,y)$ differentiable at the origin? What is $f'(0,a)$ when $a$ is a vector? Feb3 answered Is $f(x,y)$ differentiable at the origin? Feb3 awarded Revival Feb2 revised Binary search tree. Counting. deleted 1 character in body Feb2 answered Let $g: [a, b] \rightarrow \mathbb R$ integrable and $g \ge 0$. If $\int_a^b g = 0$
