The eagle who tormented Prometheus, Aethon, was the child of the monsters Typhon and Echidna. [3] In English, aithôn may be written Aethon, Aithon or Ethon. [4] In Greek and Roman mythology there are a number of characters known as Aethon. Most are horses, variously belonging to: Helios [5] Ares [6] Hector [7] Pallas [8] Hades
Mestra had the ability to change her shape at will, a gift of her rapist Poseidon according to Ovid. [6] Erysichthon exploited this gift in order to sate the insatiable hunger with which he had been cursed by Demeter for violating a grove sacred to the goddess. [7]
Achaeus of Eretria (Ancient Greek: Ἀχαιός ὁ Ἐρετριεύς; born 484 BC in Euboea) was a Greek playwright and author of tragedies and satyr plays.He is ...
Using row operations to convert a matrix into reduced row echelon form is sometimes called Gauss–Jordan elimination. In this case, the term Gaussian elimination refers to the process until it has reached its upper triangular, or (unreduced) row echelon form. For computational reasons, when solving systems of linear equations, it is sometimes ...
The concept of a coarsely-ruled grating used at grazing angles was discovered by Albert Michelson in 1898, [1] where he referred to it as an "echelon". However, it was not until 1923 that echelle spectrometers began to take on their characteristic form, in which the high-resolution grating is used in tandem with a crossed low-dispersion grating.

In linear algebra, the Hermite normal form is an analogue of reduced echelon form for matrices over the integers Z.Just as reduced echelon form can be used to solve problems about the solution to the linear system Ax=b where x is in R n, the Hermite normal form can solve problems about the solution to the linear system Ax=b where this time x is restricted to have integer coordinates only.
Similarly, the more precise term for U is that it is the row echelon form of the matrix A. Example ... Matrix Calculator with steps, including LU decomposition,
