  • Conics in Polar Coordinates

    • Polar coordinates allow conic sections to be expressed in an elegant way.
    • With this definition, we may now define a conic in terms of the directrix: $x=±p$, the eccentricity $e$, and the angle $\theta$.
    • Thus, each conic may be written as a polar equation in terms of $r$ and $\theta$.
    • For a conic with a focus at the origin, if the directrix is $x=±p$, where $p$ is a positive real number, and the eccentricity is a positive real number $e$, the conic has a polar equation:
    • For a conic with a focus at the origin, if the directrix is $y=±p$, where $p$ is a positive real number, and the eccentricity is a positive real number $e$, the conic has a polar equation:
  • Eccentricity

    • The eccentricity, denoted $e$, is a parameter associated with every conic section.
    • The value of $e$ is constant for any conic section.
    • This property can be used as a general definition for conic sections.
    • The value of $e$ can be used to determine the type of conic section as well:
    • Explain how the eccentricity of a conic section describes its behavior
  • What Are Conic Sections?

    • A conic section (or simply conic) is a curve obtained as the intersection of the surface of a cone with a plane.
    • A focus is a point about which the conic section is constructed.
    • A conic section is the locus of points $P$ whose distance to the focus is a constant multiple of the distance from $P$ to the directrix of the conic.

  • Nonlinear Systems of Equations and Problem-Solving

    • A conic section (or just conic) is a curve obtained as the intersection of a cone (more precisely, a right circular conical surface) with a plane.
    • In analytic geometry, a conic may be defined as a plane algebraic curve of degree 2.
    • The type of a conic corresponds to its eccentricity.
    • Conics with eccentricity less than $1$ are ellipses, conics with eccentricity equal to $1$ are parabolas, and conics with eccentricity greater than $1$ are hyperbolas.
    • Nonlinear systems of equations, such as conic sections, include at least one equation that is nonlinear.
  • Parabolas As Conic Sections

    • Parabolas are one of the four shapes known as conic sections, and they have many important real world applications.
    • In mathematics, a parabola is a conic section, created from the intersection of a right circular conical surface and a plane parallel to a generating straight line of that surface.
    • In the diagram showing the parabolic conic section, a red line is drawn from the center of that circle to the axis of symmetry, so that a right angle is formed.
    • Describe the parts of a parabola as parts of a conic section
  • Types of Conic Sections

    • Conic sections are formed by the intersection of a plane with a cone, and their properties depend on how this intersection occurs.
    • Conic sections are a particular type of shape formed by the intersection of a plane and a right circular cone.
    • There is a property of all conic sections called eccentricity, which takes the form of a numerical parameter $e$.
    • The four conic section shapes each have different values of $e$.
    • This figure shows how the conic sections, in light blue, are the result of a plane intersecting a cone.
  • Parts of an Ellipse

    • Ellipses are one of the types of conic sections.
    • An ellipse is a conic section, formed by the intersection of a plane with a right circular cone.
    • All conic sections have an eccentricity value, denoted $e$.
