]]> Check the derivative. Native OpenMath Well done! Compute the derivative of ${fom}
Native Native Simplify[( )-D[,x]] Native Native Length[Variables[Simplify[( )-D[,x]]]] You wrote that Native Native is the derivative of Native Native . That's correct! --> CurrentNodeElement.setAttribute ( "indicator", "1" ); intermediary results NodeList elListOMA = CurrentNodeElement.getElementsByTagName("OMA"); int nrOMA = elListOMA.getLength(); nrOMA redirect to rule Wrong! This is an elementary function. You should know the answer! NodeList elListOMA = CurrentNodeElement.getElementsByTagName("OMA"); int nrOMA = elListOMA.getLength(); nrOMA redirect to rule Wrong!
