5 is a Fermat prime, a Mersenne prime exponent, as well as a Fibonacci number. 5 is the first congruent number, as well as the length of the hypotenuse of the smallest integer-sided right triangle, making part of the smallest Pythagorean triple (3, 4, 5). [1] 5 is the first safe prime [2] and the first good prime.
The expressions "A includes x" and "A contains x" are also used to mean set membership, although some authors use them to mean instead "x is a subset of A". [2] Logician George Boolos strongly urged that "contains" be used for membership only, and "includes" for the subset relation only.
In physical terms, the divergence of a vector field is the extent to which the vector field flux behaves like a source or a sink at a given point. It is a local measure of its "outgoingness" – the extent to which there are more of the field vectors exiting from an infinitesimal region of space than entering it.
Flip cameras' video quality was unusually good for their prices and sizes. [8] They can record videos at different resolutions. FlipHD camcorders digitally record high-definition video at 1280 x 720 resolution using H.264 video compression, Advanced Audio Coding (AAC) audio compression and the MP4 file format, while the older models used a 640 x 480 resolution.

The vast majority of these 2 18 different rules [59] produce universes that are either too chaotic or too desolate to be of interest, but a large subset do display interesting behaviour. A further generalization produces the isotropic rulespace, with 2 102 possible cellular automaton rules [60] (the Game of Life again being one of them). These ...
2.5D (basic pronunciation two-and-a-half dimensional) perspective refers to gameplay or movement in a video game or virtual reality environment that is restricted to a two-dimensional (2D) plane with little to no access to a third dimension in a space that otherwise appears to be three-dimensional and is often simulated and rendered in a 3D digital environment.
Modern Arabic mathematical notation is a mathematical notation based on the Arabic script, used especially at pre-university levels of education. Its form is mostly derived from Western notation, but has some notable features that set it apart from its Western counterpart.
