2: Lines and Parabolas

( \newcommand{\kernel}{\mathrm{null}\,}\)

  • 2.1: Lines
    The notion of line or straight line was introduced by ancient mathematicians to represent straight objects (i.e., having no curvature) with negligible width and depth. Lines are an idealization of such objects.
  • 2.2: Equations of Lines and Quadratic Functions
    A quadratic function is a polynomial function in one or more variables in which the highest-degree term is of the second degree.
  • 2.3: Curve Intersection
    The intersection of two or more objects is a new object that lies in each of original objects. An intersection can have various geometric shapes, but a point is the most common in 2D space.
  • 2.4: Quadratic Inequalities
    We solve quadratic equations by either factoring or using the quadratic formula.
