Volume of a pencil A pencil sharpened at both ends is formed of a cylindrical barrel together with two conical points. The pencil measures 110mm from tip to tip, has radius $r$ mm, and the cylindrical barrel is $h$ mm...
The volume of a cylinder with radius $r$ and height $h$ is $\pi r^2 h$. The volume of a right circular cone with base radius $r$ and height $x$ is $\frac{1}{3} \pi r^2 x$. Then, the total volume of the pencil is $\pi r^2 h + \frac{1}{3} \pi r^2 x + \frac{1}{3} \pi r^2 y = \pi r^2 ( h + \frac{x + y}{...

An inequality involving fractions and a minimum It can be proved easily by contradiction that > if $a,b,c,d$ are positive numbers, then $$\frac{a+b}{c+d} \geq \min\Big\\{ \frac{a}{c},\frac{b}{d}\Big\\}.$$ I am _not...
$$\frac{a+b}{c+d}$$ is the “mediant” of the fractions $\frac ac$ and $\frac bd$ – more precisely, the mediant of the ordered pairs $(a, c)$ and $(b, d)$. Your observation is the “mediant inequality”: If $a, b, c, d > 0$ then $$ \frac ac < \frac bd \quad \Longrightarrow \quad \frac ac < \frac{a+b}{c+...

Lower bound for expectation of absolute sum of Rademacher Let $\epsilon_i$ be i.i.d. Rademacher random variables (i.e., $\epsilon_i$ takes value $\pm 1$ with equal probability). The upper bound $\mathbb{E} |\sum_{i=1}...
My answer here gives an explicit formula for $\mathbb{E}\left|\sum_{i=1}^{2n} \epsilon_i\right|$. You can get the lower bound $$\mathbb{E}\left|\sum_{i=1}^{2n} \epsilon_i\right|\geq \sqrt{n}, \tag1$$ if you combine (1) with the bound at the link there.

Nakiri bōchō
While the nakiri bōchō is sharpened from both sides, the usuba bōchō is sharpened only from one side, a style known as kataba in Japanese. The sharpened side is usually the right side for a right hand use of the knife, but knives sharpened on the left side are available for left hand use. wikipedia.org
