## Is there a way to have Shadow Hand save DCs based on Charisma?

I am playing a Spellthief/Rogue and just picked up the Martial Study feat to gain access to Shadow Hand maneuvers. Shadow Hand is a Swordsage-exclusive school and its maneuvers key off Wisdom for their save DCs, but as a Spellthief, I boosted my Charisma and my Wisdom is pretty low. Is there any way to […]

## Triangular prism, centroid of a triangle

Let $ABCA_1B_1C_1$ be a triangular prism. There is a point $T\in\Delta ABC$. Let $T_1$ be a centroid of $\Delta A_1C_1T$. If the following holds: $$\overrightarrow{A_1T_1}=\frac{1}{3}\overrightarrow{A_1A}+\frac{1}{9}\overrightarrow{A_1B_1}+\frac{4}{9}\overrightarrow{A_1C_1}$$ prove that $T$ is the centorid of $\Delta ABC$. My attempt: I wanted to use the following fact: Let $\overline{AT}$ be a median to $\overline{BC}$. Then: $$\overrightarrow{AT}=\overrightarrow{AB}+\overrightarrow{AC}=\overrightarrow{AB}+\frac{\overrightarrow{BC}}{2}=\overrightarrow{AC}-\frac{\overrightarrow{BC}}{2}$$ because a median […]

## nilpotent uniform pro-$p$ groups of dimension 2

I read in a paper that all nilpotent uniform pro-$p$ groups of dimension $\leq 2$ are Abelian (Prime Decomposition and the Iwasawa $\mu$-Invariant by Hajir-Maire, Math. Proc. of the Camb. Phil. Soc. (2019) Section 5.1). This is probably obvious, but I am unable to prove this nor have I seen a reference. This would mean […]

## $\lim_{r\to 0}\int_C \log(1-e^{2i\pi z})dz=0$ for quarter circle $C$ from $ri$ to $r$

Consider the quarter circle from $z=ri$ to $z=r$ for $r>0$. Denote this quarter circle by $C$. I would like to show that $\lim_{r\to 0}\int_C \log(1-e^{2i\pi z})dz=0.$ How can I evaluate this limit? My rough idea is that $\log(1-e^{2i\pi z}) \sim \log r$ and the length of $C \sim r$, so we use \$r\log r […]

## Two projectiles at an initial height with a missing angle of projection

David and Goliath are testing what they learned in school, that the distance travelled by launching a projectile is dependent on a range of variables; the launch angle, height and velocity of projection. As Goliath is significantly taller, David decides to throw a small projectile while standing on a ladder so that he is throwing […]
