Re: Integration problem

Hi;

They are the same, they just disagree by a constant. When you integrate you produce a family of curves. That is what the C is.

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
