A formula for computing the trigonometric identities for the one-third angle exists, but it requires finding the zeroes of the cubic equation 4x 3 − 3x + d = 0, where is the value of the cosine function at the one-third angle and d is the known value of the cosine function at the full angle.
Any real number can be written in the form m × 10 ^ n in many ways: for example, 350 can be written as 3.5 × 10 2 or 35 × 10 1 or 350 × 10 0. In normalized scientific notation (called "standard form" in the United Kingdom), the exponent n is chosen so that the absolute value of m remains at least one but less than ten ( 1 ≤ | m | < 10 ).
It can be named by its Schläfli symbol {4,3 8}, being composed of 3 9-cubes around each 8-face. It is sometimes called a dekeract, a portmanteau of tesseract (the 4-cube) and deka-for ten (dimensions) in Greek, It can also be called an icosaronnon or icosa-10-tope as a 10 dimensional polytope, constructed from 20 regular facets.
3. Also used in place of \ for denoting the set-theoretic complement; see \ in § Set theory. × (multiplication sign) 1. In elementary arithmetic, denotes multiplication, and is read as times; for example, 3 × 2. 2. In geometry and linear algebra, denotes the cross product. 3.

CTAN was officially announced at the EuroTeX conference at Aston University, 1993. The WEB server itself is maintained by Gerd Neugebauer. The WEB server itself is maintained by Gerd Neugebauer. The English site has been stable since the beginning, but both the American and the German sites have moved thrice.
The four fixed parameters used are complex, with affixes z 1 = 50 - 30i, z 2 = 18 + 8i, z 3 = 12 - 10i, z 4 = -14 - 60i. The affix point z 5 = 40 + 20i is added to make the eye of the elephant and this value serves as a parameter for the movement of the "trunk".
In the tables of knots and links in Dale Rolfsen's 1976 book Knots and Links, extending earlier listings in the 1920s by Alexander and Briggs, the Borromean rings were given the Alexander–Briggs notation "6 3 2", meaning that this is the second of three 6-crossing 3-component links to be listed.
