Barrow was the first to formalise a method of
finding tangents to a curve by defining the
tangent as the limit of a chord as the points
approach each other.
25

Leibniz derived the notation dy/dx to represent
the tangent
26

The creator of the symbols f', f" etc to
represent the cascade of derived functions or
derivatives of a function is Joseph Louis
Lagrange.

Fermat was the first to investigate maxima and
minima by considering when the tangent to the
curve was parallel to the x-axis - i.e. finding
maxima and minima by calculating when the
derivative of the function was 0
