The celestial sphere for observers in Seattle and any other observer at the same latitude (47Â° N) on the Earth is shown above. For another more detailed example, let's choose Los Angeles at latitude 34Â° N. The NCP is therefore 34 degrees above the north horizon.
Euler number. For other uses, see List of things named after Leonhard Euler Â§ Euler's numbers. In mathematics, the Euler numbers are a sequence En of integers (sequence A122045 in the OEIS) defined by the Taylor series expansion. where cosh t is the hyperbolic cosine. The Euler numbers appear as a special value of the Euler polynomials.
Euler describes 18 such genres, with the general definition 2 m A, where A is the exponent of the genre (i.e. the sum of the exponents of 3 and 5) and 2 m (where m is an indefinite number, small or large, so long as the sounds are perceptible), expresses that the relation holds independently of the number of octaves concerned.
