For example, in base-2 scientific notation, the number 1001 b in binary (=9 d) is written as 1.001 b × 2 d 11 b or 1.001 b × 10 b 11 b using binary numbers (or shorter 1.001 × 10 11 if binary context is obvious).
A vector treated as an array of numbers by writing as a row vector or column vector (whichever is used depends on convenience or context): = (), = Index notation allows indication of the elements of the array by simply writing a i, where the index i is known to run from 1 to n, because of n-dimensions. [1]
Raising and lowering indices are a form of index manipulation in tensor expressions. ... (0,2) tensor is a bilinear form. ... β = l = 1, 2, 3;
On a single-step or immediate-execution calculator, the user presses a key for each operation, calculating all the intermediate results, before the final value is shown. [1] [2] [3] On an expression or formula calculator, one types in an expression and then presses a key, such as "=" or "Enter", to evaluate the expression.
The multiplication sign (×), also known as the times sign or the dimension sign, is a mathematical symbol used to denote the operation of multiplication, which results in a product. [1] The symbol is also used in botany, in botanical hybrid names. The form is properly a four-fold rotationally symmetric saltire. [2]
Graphs of y = b x for various bases b: base 10, base e, base 2, base 1 / 2 . Each curve passes through the point (0, 1) because any nonzero number raised to the power of 0 is 1. At x = 1, the value of y equals the base because any number raised to the power of 1 is the number itself.
Index notation is often the clearest way to express definitions, and is used as standard in the literature. The entry in row i, column j of matrix A is indicated by (A) ij, A ij or a ij. In contrast, a single subscript, e.g. A 1, A 2, is used to select a matrix (not a matrix entry) from a collection of matrices.
The third stage searches for a power s of the generator g which, when multiplied by the argument h, may be factored in terms of the factor base g s h = (−1) f 0 2 f 1 3 f 2 ···p r f r.
