In mathematics, a cube root of a number x is a number y such that y 3 = 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.
Cube Route is a fantasy novel by British-American writer Piers Anthony, the twenty-seventh book of the Xanth series. Pangrammatic window. The shortest known published pangrammatic window, a stretch of naturally occurring text that contains all the letters in the alphabet, is found on page 98 of the 2004 First Mass Market Edition.
2 π / 7 {\displaystyle 2\pi /7} satisfy cubic equations. Given the cosine (or other trigonometric function) of an arbitrary angle, the cosine of one-third of that angle is one of the roots of a cubic. The solution of the general quartic equation relies on the solution of its resolvent cubic.
Doubling the cube, also known as the Delian problem, is an ancient: 9 geometric problem. Given the edge of a cube, the problem requires the construction of the edge of a second cube whose volume is double that of the first.
In arithmetic and algebra, the cube of a number n is its third power, that is, the result of multiplying three instances of n together. The cube of a number or any other mathematical expression is denoted by a superscript 3, for example 2 3 = 8 or (x + 1) 3. The cube is also the number multiplied by its square: n 3 = n × n 2 = n × n × n.
The cube root law is an observation in political science that the number of members of a unicameral legislature, or of the lower house of a bicameral legislature, is about the cube root of the population being represented.
A root of degree 2 is called a square root (usually written without the n as just ) and a root of degree 3, a cube root (written ). Roots of higher degree are referred by using ordinal numbers, as in fourth root, twentieth root, etc. The computation of an n th root is a root extraction.
Cubic function. Graph of a cubic function with 3 real roots (where the curve crosses the horizontal axis—where y = 0 ). The case shown has two critical points. Here the function is f(x) = (x3 + 3x2 − 6x − 8)/4. In mathematics, a cubic function is a function of the form that is, a polynomial function of degree three.
