You could think of it as: the numerical work uses finite precision but the symbolic work uses infinite precision. Put another way, how high does the precision of the numerical routine need to be such that symbolic routine is faster? -- Dr Jon D Harrop, Flying Frog Consultancy http://www.ffconsultancy.com
