### Understanding Conic Sections: Circles and Ellipses

In this lesson, we will explore two important conic sections: circles and ellipses. These geometric shapes are defined by specific algebraic equations, which we will analyze and interpret.

#### Equation of a Circle

The general equation of a circle with center (h, k) and radius r is given by:
\[ (x - h)^2 + (y - k)^2 = r^2 \]

In the example provided, we have a circle centered at the origin (0, 0) with a radius squared equal to 13. This is represented by the equation:
\[ x^2 + y^2 = 13 \]

- **Graph Description:** On the coordinate plane, this circle has its center at the origin and a radius of \(\sqrt{13}\).

#### Equation of an Ellipse

The standard form of an ellipse with center (h, k) is:
\[ \frac{(x - h)^2}{a^2} + \frac{(y - k)^2}{b^2} = 1 \]
where \(2a\) and \(2b\) are the lengths of the major and minor axes, respectively.

In the given equation of the ellipse:
\[ \frac{x^2}{16} + \frac{y^2}{4} = 1 \]

- **Graph Description:** This ellipse is centered at the origin (0, 0). By comparing to the standard form, we see that \(a^2 = 16\) and \(b^2 = 4\), giving us:
  - The length of the semi-major axis \(a = 4\)
  - The length of the semi-minor axis \(b = 2\)

Thus, this ellipse extends 4 units along the x-axis and 2 units along the y-axis from the center.

These equations illustrate the fundamental properties and graphical representations of circles and ellipses, aiding in the understanding of conic sections in algebra and geometry.
