“has conegut l'amor ?” no, però conec la teoria de categories. conec l'algebra. conec la geometria. sé vore el món en una varietat llisa i el cel en la categoria derivada. sé com aguantar l'infinit a la seqüència exacta estàndard i l'eternitat en la cohomologia .

That's sooo true. Sometimes you see people saying "learning math is impossible if you're not a genius", but while it's true that some people learn more quickly than others, any person can learn any piece of math if they're motivated enough

Mostre que 4^n-1 é divisível por 3, para todo n natural. Por fatoração? Não. Por indução? Não. Seja A a matriz 2 1 1 1 2 1 1 1 2 Diagonalizando ortog. mostramos que a entrada (2,1) de A^n é (4^n-1)/3. Como A é uma matriz sobre Z então A^n tbm, e assim (4^n-1)/3 é inteiro. ◻️
