Let f(x, y) be an nth degree polynomial in x and y. In general, a straight line will cross the zero set of f in n locations [1]. Newton defined a diameter to be any line that crosses the zero set of f exactly n times. If f(x, y) = x² + y² − 1 then the zero set of f is a circle and diameters of the […] The post Newton diameters first appeared on John D. Cook.
