Historical Note on Integral Calculus
The origins of integral calculus can be traced back to the ancient Greek mathematicians' attempts to calculate the area of a circle.

may have been the earliest such, with his method of exhaustion, dating from about $360$ BCE.

The techniques were used and expanded upon in his work by, to calculate areas and volumes of curvilinear figures.

These techniques are often suggested as being the precursors to integral calculus.

, in his of $1615$, devised a method of finding the volume of a solid of revolution by slicing it into thin disks, calculating the volume of each, and then adding those volumes together.

expanded upon this in his of $1635$.

arithmetized 's ideas in his of $1656$.

Much of the early work developing integral calculus was done by.

His initial work on this seems to have been achieved during the years $1665$ to $1667$ when he was at home in Woolsthorpe.

At the same time that was arranging his thesis,  was publishing many papers himself on the same subject.

The rigorous treatment of the subject was developed later, by, and.
