[Tutor] integration of polynomials in Python

[Deirdre Saoirse Moen]

>  What can I do to make it integrate?


Oh geez, I had calculus in 1976. If I get it wrong, don't yell too loudly. :)


A simple integral is simply the reverse of the differential.

So, given the equation:

2x^2 + 4x + 3 = 0

The differential would be:

4x + 4

For that equation, the process would be something like:

The first exponent coefficient (you call this 'deg') is 1; it will be 
increased 1 to 2;
You also divide by the new coefficient:

Thus:

  (4/2)x^2 + (4/1)x + k = 2x^2 + 4x + k

There's always a k (because that x^0 component drops off when you do 
the differential).
