could someone enlighten us as to the precise relation****p between
differentiation and integration. what i had in mind when visualising
the concepts of diff and int was that diff is basically the rate of
change of one variable with respect to another at a point in the path
of its function and that int is basically the reverse process whereby
one obtains the function of the relation****p between two variables in
the first order from the function at a point in its path.
