FOLLOW THIS OFFICIAL INSTRUCTION TO SWITCH FROM PANDOC TO LATEXML BACKEND. Now I have a conditional equation: $$ {{\partial \Phi } \over {\partial {X_{}}}} = - 78.9 {X_{}} < 0.34,\\ - 628.3 {X_{}} \ge 0.34 $$ Can this equation be displayed correctly in LaTeXML? I also want to reference Eq. ([eq:comp]). INTERESTING. IN AN EQUATION, IF I PLACE “\%" INSIDE “", IT’S STILL “\%", I.E., I CANNOT GET RID OF THE ANTI-BACKLASH! Directional quotation mark: “one" and “two".
