How to create a differentiation function ?

Is there any way to create a function that will return the derivative of any function passed to it? What is the general way to do it??

I don't think it's possible. But with a little effort, you can do it for simpler functions.

Consider a(x)^b for example. Scan the input as a string and extract a, b values and apply the formula. This is not even 1% of differentiation though. As far as my knowledge goes, we can't do differentiation.

But how, sir? I mean, is if-else the only way? Maybe there's an algorithm or some formula?

But there is NumPy in Python which has a diff() function for derivative... It can give an answer for any function, polynomial entered... Now I wonder, how did they make that?
