Rotation of Axes

Learning Objectives In this section, you will: As we have seen, conic sections are formed when a plane intersects two right circular cones aligned tip to tip and extending infinitely far in opposite directions, which we also call a cone. The…

The Parabola

Learning Objectives In this section, you will: Figure 1 Katherine Johnson’s pioneering mathematical work in the area of parabolic and other orbital calculations played a significant role in the development of U.S space flight. (credit: NASA) Katherine Johnson is the pioneering NASA mathematician…

The Hyperbola

Learning Objectives In this section, you will: What do paths of comets, supersonic booms, ancient Grecian pillars, and natural draft cooling towers have in common? They can all be modeled by the same type of conic. For instance, when something moves…

The Ellipse

Learning Objectives In this section, you will: Figure 1 The National Statuary Hall in Washington, D.C. (credit: Greg Palmer, Flickr) Can you imagine standing at one end of a large room and still being able to hear a whisper from a person…
