passwi meia hora encucado matutando como que eu tinha provado a injetividade de uma função que não era injetiva, só aí percebi que era pq eu tinha usado um resultado para homomorfismos mas a função não é um homomorfismo #mathsky #mathtwt

Due to a long string of stormy events, Galois groups have indeed been heavenly company this year. The carcasses-laden floods recede from time to time but froth on.

Field automorphisms map domains back onto themselves. Members of a domain may swap places but aren't really going anywhere.

Wait, is this #mathtwt or late capitalism we're talking about?

Sure, commiserate with difficulties with math. But we're coming across volumes and volumes of content depicting the subject as an enemy without anyone saying, "Math is hard? Hey, so are diving and rock climbing. Challenge and joy can be two sides of the same coin."

How liberating even this very simple opportunity to tap on your visual imagination would feel after a long day in a "Don't think; don't ask" corporate culture.

The answer is in #TheHeartofGenius E18. Half-angle formulae were used in H's solution. DM if you do need help.

Isomorphic graphs (#TheHeartofGenius E31) are graphs, i.e. sets of connections and points, with the same structure even though they may look different and have different labels.

Bonne Projection -- from Wolfram MathWorld The Bonne projection is a map projection that resembles the shape of a heart. Let phi_1 be the standard parallel, lambda_0 the central meridian, phi be the latitude, and lambda the longitude on a unit sphere. Then x = rhosinE (1) y = cotphi_1-rhocosE, (2) where rho = cotphi_1+phi_1-phi (3) E = ((lambda-lambda_0)cosphi)/rho. (4) The illustrations above show Bonne projections for two different standard parallels. The inverse formulas are phi = cotphi_1+phi_1-rho (5) lambda =...
