This is a good question. :) Sympy expressions are immutable, so it's necessary to rebuild the whole expression with the replacements applied. I did not want to cope with this, so I just intended to write a function that finds all occurrences of a certain pattern (for example sin(x)/cos(x)) in an expression. Using this, I could just pass over the job to subs. Of course this is quite inefficient, but it should work. :) Vinzent --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sympy" group.
