Study Notes
Circle and Its Equation
- Equation of a circle: ((x - h)^2 + (y - k)^2 = r^2).
- Center of circle (C) is represented by the ordered pair ((h, k)).
- When the radius (r) equals zero, the graph becomes a single point.
Parabola Properties
- Standard form of a parabola with vertex ((-3, -1)) and directrix (y = -\frac{3}{4}) is derived using the vertex and position of directrix.
- The equation of a parabola can depend on its orientation and focus location.
Hyperbola Characteristics
- The line segment joining the vertices of a hyperbola is known as the transverse axis.
- The midpoint between the focus and the directrix is called the latus rectum.
Ellipse Equation and Properties
- An ellipse centered at ((1, 2)) with a horizontal major axis can be expressed in standard form:
- Example: (\frac{(x-2)^2}{841} + \frac{(y-1)^2}{441} = 1).
- Focal distance and lengths of major/minor axes contribute to the ellipse's equation.
Hyperbola Facts
- Hyperbolas are asymmetric along the transverse axis with vertices located on the conjugate axis.
- Asymptotes are straight lines that outline the behavior of a hyperbola.
General Concepts
- Understanding the vertices, foci, directrices, and axes of conic sections is crucial.
- Familiarity with the standard forms of equations assists in graphing and solving conic-related problems.
