Fundamental Theorem of Calculus/Historical Note

Historical Note on the Fundamental Theorem of Calculus
In $1668$, published Geometriae Pars Universalis, in which the Fundamental Theorem of Calculus first makes its appearance, although only for a limited class of functions.

It is believed that the earliest complete statement and proof was made by.

This can be seen in a letter to from $1676$ or $1677$, collected as item $190$ of.

himself, in his own turn, claimed to have made the same startling realisation on reading 's $1658$ work.

In 's $1684$ article Nova Methodus pro Maximis et Minimis, published in, he takes this result as given, stating that $\int$ and $\mathrm d$ are each other's converse, with no attempt at proof.
