    [163] [164] [165] In two dimensions, the critical Sobolev inequality is ‖ ‖ ‖ ‖ for f a smooth function with compact support in R 2, is the gradient of f, and ‖ ‖ and ‖ ‖ refer respectively to the L 2 and L 1-norm. The Sobolev inequality is equivalent to the isoperimetric inequality (in any dimension), with the same best constants.

    1+9+8+2 (official title 1982 in some sources) [4] is the fifteenth studio album by the English rock band Status Quo, released on 16 April 1982. [5] [6] It was the first to include new drummer Pete Kircher, who had recently replaced John Coghlan, and also the first to credit keyboard player Andy Bown as a full member of the band.

    en.wikipedia.org/wiki/List_of_mathematical_constants

    A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]

    The computation of (1 + ⁠ iπ / N ⁠) N is displayed as the combined effect of N repeated multiplications in the complex plane, with the final point being the actual value of (1 + ⁠ iπ / N ⁠) N. It can be seen that as N gets larger (1 + ⁠ iπ / N ⁠) N approaches a limit of −1. Euler's identity asserts that is

    Later computers calculated pi to extraordinary numbers of digits (2.7 trillion as of August 2010), [4] and people began memorizing more and more of the output. The world record for the number of digits memorized has exploded since the mid-1990s, and it stood at 100,000 as of October 2006. [ 6 ]

    The square root of 2 is equal to the length of the hypotenuse of a right-angled triangle with legs of length 1. The square root of 2, often known as root 2 or Pythagoras' constant, and written as √ 2, is the unique positive real number that, when multiplied by itself, gives the number 2. It is more precisely called the principal square root ...
