The Comprehensive LaTeX Symbol List

See also the polynom package, which automaticallysolves and typesets polynomial-division problems in a similar manner.∗ These symbols are made more extensible by the MnSymbol package and even moreextensible by the yhmath package.† If you’re looking for an extensible diagonal line or arrow to be used for canceling orreducing mathematical subexpressions (e.g., “✘x + ✘ −x” ✘ or “✘ 3 + ✘ ✘✿2 5”) then considerusing the cancel package.‡ With an optional argument, \sqrt typesets nth roots. For example,“\sqrt[3]{abc}” produces “ 3√ abc ” and “\sqrt[n]{abc}” produces “ n√ abc ”.Table 158: overrightarrow Extensible Accents=⇒abc \Overrightarrow{abc}Table 159: yhmath Extensible Accentsâbc \wideparen{abc} È abc \widetriangle{abc}˚âbc\widering{abc}57
