TagSet (/:) works fine for expressions of the form: f/: g[f[x_]] := stuff but I would like to use TagSet for the following type of operation: f/: Plus[Times[a_,f[x_]],Times[b_,f[x_]]] := (a+b) f[x] (for instance). 1) In general, is there a way to use TagSet on something of the form f/: g[h[f[x]]] :=stuff 2) Is there a simple way to implement the specific instance of (1) where g is Plus and h is Times? Note: if the answer is different, take the following two options: (a) f is my own function and therefore I'm happy to change its Attributes. (b) f is a predefined function for which I would rather not change its Attributes. Thank you --Jeff Brown jsbrown0 at basalt.mines.colorado.edu (NeXT-mail fine)
