derivatives and indefinate integrals

[JeffG]

Are there any calulators for calculus that can solve indefinate integrals, or perform differentiation?

I'm looking to input a function and get the result as a function, not as a value.

Thanks,

Jeff

four come to mind.

Hp49G
Ti-89
Hp48G series (nearly = to 49g with free software)
Casio FX 2.0

There might be others I have overlooked, perhaps Sharp also has a CAS type calc available.

As Ron's response indicates (and I learned), there are
calculators that return functions for derivatives and
indefinite integrals, although IMHO if you're going to do
this, give it up and use Mathematica. You'll be glad you
did.

I IMHO would definitely recommend the 49G, though the 48 series are very good for that but much slower.
