Suppose you have: eq=lhs==rhs Using FullForm is often a good start when trying to understand the way Mathematica puts things together: FullForm[eq] So your tools should look like: First[eq] Last[eq] Hope this helps, **************************************** Jean-Marie THOMAS mailto:jmthomas at agat.net Conseil et Audit en Ingenierie de Calcul Strasbourg, France http://www.agat.net **************************************** -----Original Message----- From: David P.

Something like: In[2]:= LHS[eq1] Out[2]:= Sin[x] TIA. -- David ->(Signature continues here)
