This YouTube video discusses how to draw a hyperbola and what its elements are. The presenter defines a hyperbola as a geometric location of points where the difference in distance from two fixed points is always constant. They outline the steps to draw a hyperbola, including finding the vertices and foci, using the Pythagorean theorem to find the distance "b," and drawing the asymptotes. Important measurements of the hyperbola, such as the distance between the foci and the side rectum, are explained. This video provides a helpful introduction to understanding hyperbolas.

• 00:00:00 In this section, the video explains how to draw a hyperbola and what its elements are. Before delving deeper into how to draw one, the presenter explains that a hyperbola is a geometric location of points, whose difference in distance from two fixed points is always constant. The video provides various examples of different types of hyperbolas and emphasizes that these two curved lines (that may seemingly form a straight line) are called asymptotes, which are crucial to graphing hyperbolas. To draw a hyperbola, the presenter advises drawing a rectangle first, and then using the vertices to plot the hyperbola. Finally, the center of the hyperbola is located, and the vertices are placed on the axis that corresponds to the opening of the hyperbola.
• 00:05:00 In this section, the speaker explains how to locate the vertices and foci of a hyperbola, as well as the distance from the focus to the center (called "c") and the distance from a vertex to the center (called "a"). They then draw a circle with its center at the center of the hyperbola and passing through the foci, allowing them to find the distances "c" and "a" and use the Pythagorean theorem to find the distance "b." With this information, the speaker is able to draw the asymptotes and finally draw the hyperbola itself. The hyperbola is defined as the set of all points whose difference in distance from the fixed points (the foci) is constant.
• 00:10:00 In this section, the concept of fixed points on a hyperbola (the foci) is discussed, and how the difference between the distances from any point on the hyperbola to each focus is always constant. The distance between the vertices of the hyperbola, the distance from the focus to the center (and thus to the other focus), and the distance between the two foci are explained as important measurements of the hyperbola. The side that passes through the focus and touches the hyperbola is explained and its measurement (known as the "side rectum") is discussed. The measurements "a", "b", and "c" are explained and how they form a right triangle. These are important concepts to understand when working with hyperbolas.
