Hence, zero is the (global) minimum of the square function. The square x 2 of a number x is less than x (that is x 2 < x) if and only if 0 < x < 1, that is, if x belongs to the open interval (0,1). This implies that the square of an integer is never less than the original number x.
Denotes square root and is read as the square root of. Rarely used in modern mathematics without a horizontal bar delimiting the width of its argument (see the next item). For example, √2. √ (radical symbol) 1. Denotes square root and is read as the square root of. For example, +. 2.

The Cartesian square of a set X is the Cartesian product X 2 = X × X. An example is the 2-dimensional plane R 2 = R × R where R is the set of real numbers: [1] R 2 is the set of all points (x,y) where x and y are real numbers (see the Cartesian coordinate system).
Among the fonts in widespread use, [6] [7] full implementation is provided by Segoe UI Symbol and significant partial implementation of this range is provided by Arial Unicode MS and Lucida Sans Unicode, which include coverage for 83% (80 out of 96) and 82% (79 out of 96) of the symbols, respectively.
The stolen vehicle was entered into law enforcement databases, and was spotted in a parking lot by a police officer on Christmas Day in Oklahoma City, some 200 miles away.
The space described above is commonly denoted (F X) 0 and is called generalized coordinate space for the following reason. If X is the set of numbers between 1 and n then this space is easily seen to be equivalent to the coordinate space F n. Likewise, if X is the set of natural numbers, N, then this space is just F ∞. A canonical basis for ...
Victoria Woodhull was the first woman to run for president in the U.S. and she made her historic run in 1872 – before women even had the right to vote! She supported women's suffrage as well as welfare for the poor, and though it was frowned upon at the time, she didn't shy away from being vocal about sexual freedom.
