The gravitational potential $G_{pot}$ has units of energy per unit mass: $$ \bigg[\frac{J}{kg}\bigg] = \bigg[\frac{kg m^2}{s^2kg}\bigg] = \bigg[\frac{m^2 }{s^2}\bigg]. $$ The gravitational force is $F = - \nabla G_{pot}$ so this would lead me to believe that unit-wise, due to...

Q. Solve for $x$, $y$ and $z$ if $$(x+y)(x+z)=15, $$ $$(y+z)(y+x)=18, $$ $$(z+x)(z+y)=30. $$ Solution: I expanded each equation above as : $$x^2+xz+yx+yz=15, \tag{1}$$ $$y^2+xz+yx+yz=18, \tag{2}$$ $$z^2+xz+yx+yz=30. \tag{3}$$ Then I subtracted $(1)-(3)$, $(2)-(1)$ and $(3)-(2)$; so I got the equations...

Why do the ratios of successive values of integers $a$ and $c$, where $a^{2}+(a+1)^{2}=c^{2}$, appear to converge to $$\frac{a_{n+1}}{a_{n}},\frac{c_{n+1}}{c_{n}}\rightarrow3+2\sqrt{2}$$ I rigorously generated all the {a,c} pairs where $a^{2}+(a+1)^{2}=c^{2}$ for $a<10^6$: {3, 5}, {20, 29}, {119, 169}, {696, 985}, {4059, 5741},...

I would like to prove the following, $$\sum_{k=0}^{n-1} \text{cos}\left(\frac{2\pi k}{n} \right) = \sum_{k=0}^{n-1} \text{sin}\left(\frac{2\pi k}{n} \right) = 0$$ This is equivalent to showing that if we have a regular n-gon, all of the vectors in $\mathbb{R}^2$ pointing to every vertex...
