Thanks to the work of
Barrow, Newton and Leibniz (the creators of infinitesimal calculus), two
paths which had developed separately throughout the history of
mathematics, for over more than 20 centuries, were combined in what is now
known as integral calculus.
One
of the paths, the search for formulae to find the area of plane regions,
dates back to the ancient Greek mathematicians.
The other
path emerged to develop the concept of the derivative, by looking for a
reciprocal operation. |
