FormulaText[Object]
Returns the formula for the object as a LaTeX text.
備註: By default, values are substituted for variables.
範例: If a = 2 and f(x) = a x2, then FormulaText[f] returns 2 x2 (as a LaTeX text).
FormulaText[Object, Boolean]
Returns the formula for the object as LaTeX text. The Boolean variable determines if values are substituted for variables (true) or if variable names are shown in the text (false).
範例: If a = 2 and f(x) = a x2, then FormulaText[f, true] returns 2 x2 (as a LaTeX text) and FormulaText[f, false] returns a x2 (as a LaTeX text).
