Noun
the longest axis of an ellipse or ellipsoid; passes through the two foci
Source: WordNetFor an ellipse in canonical position (center at origin, major axis along the X-axis), the equation simplifies to : : The parameter t (called the eccentric anomaly in astronomy) is not the angle of with the X-axis (see diagram at right). Source: Internet
Coordinate systems Cartesian coordinates An east-west opening hyperbola centered at (h,k) has the equation : The major axis runs through the center of the hyperbola and intersects both arms of the hyperbola at the vertices (bend points) of the arms. Source: Internet
If one forms a rectangle with vertices on the asymptotes and two sides that are tangent to the hyperbola, the sides tangent to the hyperbola are 2b in length while the sides that run parallel to the line between the foci (the major axis) are 2a in length. Source: Internet
Since the Mach number of the flow can be appreciable, refraction makes it difficult to determine the major axis of the dipole-like sound field. Source: Internet
Here is the center of the ellipse, and is the angle between the -axis and the major axis of the ellipse. Source: Internet
It has a carrot-like shape, with the major axis extending from southwest to northeast and a wide southern part narrowing toward the north. Source: Internet
