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
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
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
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 $\circ$
What is the degree symbol? - TeX - LaTeX Stack Exchange In order to have the following output involving the degree symbol I can try \documentclass{report} \begin{document} The angle is 30$^\circ$ \end{document} However, this is an awkward manner to obtain the degree symbol - one reverts to math mode and casts an existing symbol into superscript Is there a straightforward way of obtaining the degree symbol?
Trigonometric ratios for angles greater than $90^\\circ$? The trigonometric ratios of an angle greater than $90^\\circ$ are equal to the supplementary angle's ratios I'm just clarifying this, but the ratios don't actually exist for angles greater than $90^\\
