wolfram alpha accepts latex, but it does not export to latex,
it exports plaintext,rendered images and mathematica sytax.
Is there any javascript library that converts the output to latex?
Mathematica syntax:
Cell[BoxData[FormBox[TagBox[RowBox[List[FractionBox["1", "2"], " ", RowBox[List["(", RowBox[List[RowBox[List["4", " ", SuperscriptBox["x", "2"]]], "+", "x", "+", "2"]], ")"]]]], Identity, Rule[TagBoxNote, List[Rule["Hyperlink", "1/2 (2+x+4 x^2)"]]]], TraditionalForm]], "Output", Rule[PageWidth, 500], Rule[Magnification, 1], Rule[CellMargins, List[List[0, 0], List[0, 0]]], Rule[ShowCellBracket, False], Rule[FontFamily, "Bitstream Charter"], Rule[FontSize, 14], Rule[NumberSeparator, "\[ThinSpace]"]]
Latex syntax
2x^2+\frac{x}{2} +1
