John Wallis and the “Rectification” of the Parabola [PDF]

open access: yesMathematics, 2022
The problem of the rectification of curves and the calculation (for which we shall adopt the more geometric term “flattening”) of the surface of a rotating solid generated by a curve, once the rotation axis has been fixed, were treated by John Wallis in ...
