In mathematics, a cube root of a number x is a number y such that y3 = x. All nonzero real numbers have exactly one real cube root and a pair of complex conjugate cube roots, and all nonzero complex numbers have three distinct complex cube roots. For example, the real cube root of 8, denoted , is 2, because 23 = 8, while the other cube roots of ...
The finance-centric programmable calculator from the Voyager series introduced in the 1980s. The longest running product in the HP calculator line, it remains in production. Various models exist, the latest in 2008. HP-14B: 1988 Finance calculator with 12 digits precision and algebraic logic. It has 130 functions, 41 keys, and an LCD display ...
TI-BASIC is the official [1] name of a BASIC -like language built into Texas Instruments (TI) 's graphing calculators . TI-BASIC is a language family of three different and incompatible versions, released on different products: TI rarely refers to the language by name, but the name TI-BASIC has been used in some developer documentation.
The other roots of the equation are obtained either by changing of cube root or, equivalently, by multiplying the cube root by a primitive cube root of unity, that is . This formula for the roots is always correct except when p = q = 0 , with the proviso that if p = 0 , the square root is chosen so that C ≠ 0 .
History. A simple arithmetic calculator was first included with Windows 1.0.. In Windows 3.0, a scientific mode was added, which included exponents and roots, logarithms, factorial-based functions, trigonometry (supports radian, degree and gradians angles), base conversions (2, 8, 10, 16), logic operations, statistical functions such as single variable statistics and linear regression.
Every digit of the root found is known to be correct, i.e., it does not have to be changed later. If the square root has an expansion that terminates, the algorithm terminates after the last digit is found. Thus, it can be used to check whether a given integer is a square number.
In mathematics, taking the nth root is an operation involving two numbers, the radicand and the index or degree. Taking the nth root is written as , where x is the radicand and n is the index (also sometimes called the degree). This is pronounced as "the nth root of x". The definition then of an nth root of a number x is a number r (the root ...
The cube function is the function x ↦ x 3 (often denoted y = x 3) that maps a number to its cube. It is an odd function, as (−n) 3 = −(n 3). The volume of a geometric cube is the cube of its side length, giving rise to the name. The inverse operation that consists of finding a number whose cube is n is called extracting the cube root of n ...
