> Then when we try to simplify the above, we get the error:Yeah, and this is connected to the changes in how we print "symbolic derivatives" from a year or two ago. I don't want to touch this code because of the potential to mess up how theoretical physics folks need this, but I think it should look more like Maxima or something that just leaves these unevaluated. I don't know that this will get fixed anytime soon, though. - kcrisman -- You received this message because you are subscribed to the Google Groups "sage-edu" group.
