If a student comes to your office saying she cannot seem to understand this "limit" thingy, I wonder if you would wish to say, "Don't feel too bad, Ms Liddell. No one in our department understands limits much better than you do! Anyway, not enough to program a computer to do them. Only Wolfram has the algorithm for that." This seems unconscionable to me. But then, I didn't realize taking limits was so difficult. In order to differentiate something, obviously you have to take a limit. Yet I never heard of anything one couldn't manage to differentiate. And then having the derivative of a function would surely help in taking other limits involving that function. What's the big difficulty?
