Guys, today I was interested in brachiochrone concept from Newton. I wanted to see whether coords of brachiochrones are really multips of forces of the balls interacting in gravity. And it seems to [...] Read more

2x!=x! * x => x=2 ; just mentally imagining this; okay full computation: 1/2x^2(x-1)!(x-2)!=x!; then x(x-1)!x(x-2)!=2x!; x!x(x-2)!=2x!; x(x-2)!=2; where 0!=1 and 2*1{2-2}=2 [...] Read more

ah let's compute: (E=4pí * 9.1e-31 * 1.602e-19 = 2e-48J), now t=3e30s=h/E; but what is this? 3e30s=>3e6 km/s=c^5 =>c^n=nc, but why we used 5 dim space? if a cube has 6 vectors in? and what is [...] Read more

ono ani to netreba rátať moc si myslím n^2 je 2n a (2 * 2 * 9) je cca tých 4/36 gaussovým odhadom, alé musíte si v mysli otočiť rovnice na transponovaný tvar, aby ste to videli a odhadli ;) vypínam [...] Read more

išiel by som na to, žé základ na hocičo sa rovná nule je jednotka, teda stačí rozklad (x-5)(x-6)=0; teda len x1=5 a x2=6 😜🙂 dve minútky z hlavy 💯✔️ [...] Read more

I would say: ((108-18)/3.6)/5 => t=5s; then s=0.5at^2 => s=(0.5 * 5 * 25) => delta s=62.5m 😜💯 check of units: 0.5ms^-2s^2 => m ✔️ [...] Read more

išiel by som na to ako -w=1*0+w, teda w=-1, áno sme smart ínaf 😉 skúška: 5^--1=6-1; 5==5 ok 😜💯✔️ všetci hádam majú maturitu z matiky, či? [...] Read more

Tak prenásobme 2x a sčítajme, 6x+5x+0y=44 => x=4; dosaďme: 18-12=6/2 => y=3; No a toto bola naša chuťovečka z hlavy ^^^ [...] Read more
