Nope! Derivatives are relatively easy, you just have to program in all the
rules. There aren't rules for every integral - some you can't do, and there
are tons of different forms. When you get to advanced functions like the
trig and log, and combinations, integration has a lot of guess-and-try-it.
A symbolic differentiation program would just have to search a rule table
for a form that matched, and then figure out the derivative using the rule.
You could do a symbolic integration program that way, but it would probably
be slow and/or not have a very good range of equations it could integrate.
