Polygon

In mathematics, convex geometry is the branch of geometry studying convex sets, mainly in Euclidean space.

Doubling the edge lengths of a polygon multiplies its area by four, which is two (the ratio of the new to the old side length) raised to the power of two (the dimension of the space the polygon resides in).

In Proposition 18 he argues that there are no further convex regular polyhedra.

To calculate the total area and volume of oil contaminated sediments, Saudi Arabia relies on a polygon of influence method.

Since the slope of the convex lens surface increases outwards, separation of the rings gets smaller for the outer rings.

The Convex Computer series, as well as a number of small scale parallel machines from companies like Pyramid Technology and Alliant Computer Systems were particularly popular.

In any case, Theaetetus gave a mathematical description of all five and may have been responsible for the first known proof that no other convex regular polyhedra exist.

In mathematics and physics, the Legendre transformation or Legendre transform, named after Adrien Marie Legendre, is an involutive transformation on the real valued convex functions of one real variable.

It is divided in five vertical stripes two white stripes and three black stripes, inside which are the following elements in its upper section, the name of the society superimposed on a white convex section, over golden curvature (gold for honour).

These lenses use some form of the cassegrain design which greatly reduces the physical length of the optical assembly, partly by folding the optical path, but mostly through the telephoto effect of the convex secondary mirror which multiplies the focal length many times (up to 4 to 5 times).
