Square packing in a square is the problem of determining the maximum number of unit squares (squares of side length one) that can be packed inside a larger square of side length . If is an integer, the answer is but the precise – or even asymptotic – amount of unfilled space for an arbitrary non-integer is an open question. [ 1] The ...
Rectangle. In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be defined as: an equiangular quadrilateral, since equiangular means that all of its angles are equal (360°/4 = 90°); or a parallelogram containing a right angle. A rectangle with four sides of equal length is a square.
CodeHS was selected as one of three education technology companies to take part in the 2013 Innovation Challenge, part of the NBC Education Nation initiative. [6] Innovation Nation challenge participants CodeHS, Teachley, and GigaBryte participated in a series of challenges in October 2013, culminating in a live pitch contest broadcast live on NBC during the Education Nation Summit.
The unit, named after Blaise Pascal, is an SI coherent derived unit defined as one newton per square metre (N/m 2). [1] It is also equivalent to 10 barye (10 Ba) in the CGS system. Common multiple units of the pascal are the hectopascal (1 hPa = 100 Pa), which is equal to one millibar , and the kilopascal (1 kPa = 1000 Pa), which is equal to ...
Function (computer programming) In computer programming, a function, procedure, method, subroutine, routine, or subprogram is a callable unit[ 1] of software logic that has a well-defined interface and behavior and can be invoked multiple times. Callable units provide a powerful programming tool. [ 2] The primary purpose is to allow for the ...
In mathematics, the moving sofa problem or sofa problem is a two-dimensional idealization of real-life furniture-moving problems and asks for the rigid two-dimensional shape of the largest area that can be maneuvered through an L-shaped planar region with legs of unit width. [ 1] The area thus obtained is referred to as the sofa constant.
The rectangular function (also known as the rectangle function, rect function, Pi function, Heaviside Pi function, [ 1] gate function, unit pulse, or the normalized boxcar function) is defined as [ 2] Alternative definitions of the function define to be 0, [ 3] 1, [ 4][ 5] or undefined. Its periodic version is called a rectangular wave .
Wear OS. Wear OS (also known simply as Wear[ 8] and formerly Android Wear[ 9]) is a version of Google 's Android operating system designed for smartwatches and other wearables. [ 10][ 11][ 12] By pairing with mobile phones running Android version 6.0 "Marshmallow" or newer, or iOS version 10.0 or newer with limited support from Google's pairing ...
