In trigonometry, the law of sines, sine law, sine formula, or sine rule is an equation relating the lengths of the sides of any triangle to the sines of its angles.According to the law, = = =, where a, b, and c are the lengths of the sides of a triangle, and α, β, and γ are the opposite angles (see figure 2), while R is the radius of the triangle's circumcircle.
The "nine dots" puzzle. The puzzle asks to link all nine dots using four straight lines or fewer, without lifting the pen. The nine dots puzzle is a mathematical puzzle whose task is to connect nine squarely arranged points with a pen by four (or fewer) straight lines without lifting the pen or retracing any lines.
The vertices of triangles are associated not only with spatial position but also with other values used to render the object correctly. Most attributes of a vertex represent vectors in the space to be rendered.
In Euclidean geometry, a triangle conic is a conic in the plane of the reference triangle and associated with it in some way. For example, the circumcircle and the incircle of the reference triangle are triangle conics.
The Triangle of Life does not address the common instance of furniture toppling over during an earthquake. Copp's idea is focused on situations when a building completely collapses, falling straight down, rather than the far more common situations, when side-to-side shaking causes falling objects (such as trees, chimneys, furniture, and objects on shelves) to land on top of people.
The Big Bang theory, which explains the Evolution of the Universe from a hot and dense state, is widely accepted by physicists.. In astronomy, cosmogony is the study of the origin of particular astrophysical objects or systems, and is most commonly used in reference to the origin of the universe, the Solar System, or the Earth–Moon system.
The Egyptologists Nina M. Davies (6 January 1881 – 21 April 1965) and Norman de Garis Davies (1865–5 November 1941) [1] were a married couple of illustrators and copyists who worked in the early and mid-twentieth century drawing and recording paintings in Egypt.
