No spacing after Sigma?












6














There seems to be barely any spacing (if at all) after Sigma, making it hard to read. Is this normal? Is there any way around it? 



 $ Sigma_{v in V} alpha $

    Sigma is a normal greek letter so has no spacing just as abc has no extra spacing, if you mean summation operator then use sum which is a different character and also specified as a math operator so has different spacing.

You should use sum, not Sigma, to create a summation symbol. The sum symbol is slightly larger than Sigma when used in text style, and a whole lot larger when used in display style. In addition, the math type of sum is math-op ("math operator"), whereas the math type of Sigma is math-ord ("ordinary atom"); this strongly affects the amount of whitespace TeX inserts before and after the symbol.

Ellipse (mathématiques)

Pour les articles homonymes, voir Ellipse. L'ellipse est le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante. Section du cône ou projection du cercle. En géométrie, une ellipse est une courbe plane fermée obtenue par l’intersection d’un cône de révolution avec un plan, à condition que celui-ci coupe l'axe de rotation du cône ou du cylindre : c'est une conique d'excentricité strictement comprise entre 0 et 1. On peut également la définir comme le lieu des points dont la somme des distances à deux points fixes, dits foyers, est constante (sa construction par la méthode du jardinier est très simple). Dans la vie courante, l’ellipse est la forme qu'on perçoit en regardant un cercle en perspective, ou la figure formée par l’ombre d'un disque sur une surface plane. On retrouve aussi, en première approximation [ 1 ] , des ellipses dans les trajectoires des corps célestes (planètes, comètes ou satellites arti...

Quarter-circle Tiles

up vote 0 down vote favorite I have $99$ identical square tiles, each with a quarter-circle drawn on it like this: [asy] size(1.5cm); draw(Arc((2,0),1,90,180),red+1); draw((0,0)--(2,0)--(2,2)--(0,2)--(0,0)); [/asy] When I arrange the tiles in a $9times 11$ rectangular grid, each with a random orientation, what is the expected value of the number of full circles I form?
