- 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
- 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
- Trying to understand the arrows-only description of a natural . . .
I don't understand the question; you (rightly) say that we cannot form the composite $\tau (g) \circ \tau (f)$, then proceed to ask something about this composite
- 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
- Prove $2 (\sin (36^ {\circ})+\sin (72^ {\circ})) = \sqrt2\csc (27 . . .
7 I stumbled upon this trigonometirc identity $$2 (\sin (36^ {\circ})+\sin (72^ {\circ})) = \sqrt2\csc (27^ {\circ}) + \cot (27^ {\circ})-2$$ and find its exact value is $\sqrt {5+2\sqrt5}$ The backstory is an elementary exersice on regular polygon, note the shape in blue are both regular below
- 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
- 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 $\circ$
- 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
