Cand incepe sa plimbe patratul tot mentioneaza o curba, nu e nici o curba acolo. Patratul ala devine un fractal, nu o curba. Fractalul ala nu aproximeaza si nici nu interpoleaza curbe.

PI nu este 4 si afirmatia e falsa. Am mai vazut problema pe interneti.

Lungimea unui cerc este: 2 x pi x r, adica fix formula din videoclip. Numai ca raza unui cerc cuprins intr-un patrat cu latura de 4 este 2 asa ca formula devine: 2 x pi x 2 = 12.64
