Quadratic graph lines are U- or Ո-shaped, which is called a parabola. A linear graph can be drawn using only three points. A quadratic graph is a curve, so more points are plotted to support accuracy.

This Python project implements quadratic spline interpolation, a mathematical technique used for creating a smooth curve that passes through a set of given data points. The project leverages the SymPy ...

Abstract: This paper develops a quadratic function convex approximation approach to deal with the negative definite problem of the quadratic function induced by stability analysis of linear systems ...
