A rectangular hyperbola is a type of hyperbola that has perpendicular asymptotes and is symmetric with respect to both the x-axis and the y-axis. It is characterized by its equation, which is of the form xy = k, where k is a constant.
The study of hyperbolas dates back to ancient Greece, where mathematicians like Apollonius of Perga made significant contributions to the understanding of conic sections. The rectangular hyperbola, in particular, gained attention during the Renaissance period when mathematicians like René Descartes and Pierre de Fermat further explored its properties.
The concept of rectangular hyperbola is typically introduced in advanced high school or college-level mathematics courses, such as precalculus or analytic geometry.
Rectangular hyperbola involves several key concepts, including:
There are no distinct types of rectangular hyperbola. However, the orientation of the hyperbola can vary based on the values of k in the equation xy = k. If k > 0, the hyperbola is oriented diagonally, while if k < 0, it is oriented vertically or horizontally.
Some important properties of rectangular hyperbola include:
To find or calculate a rectangular hyperbola, you need to know the value of k in the equation xy = k. Once you have the value of k, you can plot the hyperbola by finding points that satisfy the equation.
The equation for a rectangular hyperbola is xy = k, where k is a constant.
To apply the equation of a rectangular hyperbola, you can substitute different values of x and solve for y, or vice versa. This will give you the coordinates of points on the hyperbola, which can then be plotted on a graph.
There is no specific symbol or abbreviation for rectangular hyperbola.
Some common methods for studying rectangular hyperbolas include:
Example 1: Find the equation of the rectangular hyperbola with k = 4. Solution: The equation is xy = 4.
Example 2: Determine the coordinates of points on the rectangular hyperbola xy = -9. Solution: By substituting different values of x or y, we can find points such as (3, -3) and (-3, 3).
Example 3: Graph the rectangular hyperbola xy = 1. Solution: By plotting points that satisfy the equation, such as (1, 1), (-1, -1), (2, 0.5), and (-2, -0.5), we can obtain the graph of the hyperbola.
