  • Is there a circle symbol? - TeX - LaTeX Stack Exchange
    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
    ∘ 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 corresponding
  • How do I use a circle as a math accent (larger than \mathring)?
    An example: $\mathring{I}\ \mathring{J}\ \overset{\circ}{I}\ \overset{\circ}{J}$ yields If one has a close look then one sees that the \circ over the J should be moved to the right more than the \circ over the J! Is there a way to obtain the same nice automatic positioning as with mathring?
  • pi - Is $180^\circ = 3. 14. . $? Correlating the circumference and . . .
    I'm trying to correlate $\\pi$ to the circumference and diameter of a unit circle Consider a unit circle and represent it in terms of an n-gon Join each vertex to its center The angle subtended i
  • Automatically replacing \º with $^\circ$ - LaTeX Stack Exchange
    I don't like the º-symbol, that LateX is typesetting, because it has this strange underline So I wanted to make a new-command, that's replacing \\º with $^\\circ$ and i tried to define it like thi
  • How do I put a circle around a symbol? - LaTeX Stack Exchange
    I am trying to put \\star in a circle so I can use it on my paper I could not find a proper way to do so Is there a (simple) way of doing such a custom symbol?
  • Specifying bullet type when using itemize - LaTeX Stack Exchange
    Is there a way to get a specific type of bullet instead of the filled bullets when you first activate the itemize command in LaTeX? I am trying to get hollow bullets from the start instead of using
  • What is the $\\circ$ symbol in Graph Theory - Mathematics Stack Exchange
    I have come across the following formula in Graph Theory and am trying to decipher what it means f(x ∘ y) = f(x) ∘ f(y) f (x ∘ y) = f (x) ∘ f (y) It is fairly simple but I have received a number of conflicting definitions of the " ∘ ∘ " symbol which is making it hard to interpret In some cases people where using this to represent contraction, some to represent relation, etc The
  • Letter with circle above -- not a dot -- in math mode
    I need to typeset letter with a circle above it in math \dot A does a very close result, but I need something that looks like \circ, not like \cdot Edit: there is awesome answer here, but Detexify failed for me, and I tried looking up tables, but haven't found what I needed
  • Solve $\\sin 84^\\circ \\sin(54^\\circ-x)=\\sin 126^\\circ \\sin x$.
    I tried to use trigonometry identities to transform the product in sums, but I can't simplify moreover I know the result is 30° since I solved it in a calculator, but there must be an algebraic way For context, this equation comes from solving this problem: How can I solve this geometry problem without trigonometry?
