- Is there a circle symbol? - TeX - LaTeX Stack Exchange
88 Probably this is a good chance to recall the Detexify website, where you can simply draw the symbol you want, and obtain the needed code I'm a bad illustrator, but for me, after drawing the circle, \circ was the first hit
- What operation is $\circ$? - Mathematics Stack Exchange
$\circ$ is exactly the operation given by the table, no more, no less It is not addition mod $4$, or multiplication mod $4$, or anything familiar like that The only question is whether it is a group operation So find out whether it has an identity (this should be pretty quick), and determine what that identity element is Then find out whether each element has an inverse—that is, a
- How do I use a circle as a math accent (larger than \mathring)?
In the end I'm using an even larger circle than in Caramdir's great answer: accents sets the \circ in \scriptscriptstyle; I'm using \scriptstyle To not affect the line spacing so much, I have the circle lowered and let it stick out a bit of the bounding box of the resulting accented character
- Proving $ \angle MAN = 45^\circ$ in an isosceles right triangle
Regional Mathematical Olympiad 2003 (India) Let $ABC$ be a triangle in which $AB =AC$ and $\\angle CAB = 90^{\\circ}$ Suppose that $M$ and $N$ are points on the
- Can an isosceles triangle with a $60^\\circ$ angle be proven . . .
Theorem An isosceles triangle with a $60^\circ$ angle is equilateral Two cases of this theorem are depicted below I consider any (or both) of these cases The standard proof relies on two key facts: The base angles of any isosceles triangle are equal in measure The sum of interior angles of a triangle equals a straight angle ($180^\circ$)
- symbols - Circle above a letter - TeX - LaTeX Stack Exchange
I could write a circle above the letter but it seems far a little bit Is there a way to get it down a little bit, because I really use it a lot and it takes a lot of space Here is a sample of the
- lie groups - Action of $G G^\circ$ on the roots of $G^\circ . . .
If we take $G$ a non connected algebraic group over $\mathbb C$, with $G^\circ$ its neutral component, which we assume to be reductive, we can define an action of $A:=G G^\circ$ on the weight lattice of $G^\circ$ in the following way
- Is $\pi$ equal to $180^\circ$? - Mathematics Stack Exchange
This answer is not correct: it would be correct if the part "not $\pi$ but" were deleted In fact the number $2\pi$ is literally equal to $360^\circ$ This is the definition of $\circ$
