Casuarina cristata, commonly known as belah or muurrgu, [2] is a species of flowering plant in the family Casuarinaceae and is endemic to inland eastern Australia. It is a tree with fissured or scaly bark, sometimes drooping branchlets, the leaves reduced to scales in whorls of 8 to 12, the fruit 13–18 mm (0.5–0.7 in) long containing winged ...
In trigonometry, trigonometric identities are equalities that involve trigonometric functions and are true for every value of the occurring variables for which both sides of the equality are defined.
The rhombus has a square as a special case, and is a special case of a kite and parallelogram.. In plane Euclidean geometry, a rhombus (pl.: rhombi or rhombuses) is a quadrilateral whose four sides all have the same length.
A lozenge (/ ˈ l ɒ z ɪ n dʒ / [1] LOZ-inj; symbol: ), often referred to as a diamond, is a form of rhombus.The definition of lozenge is not strictly fixed, and the word is sometimes used simply as a synonym (from Old French losenge) for rhombus.
Bila (also occasionally rendered Belah [1] [2]) is the personification of the Sun among the Adnyamathanha people. She is a solar goddess, as befitting the general trends among Australian aboriginal peoples, which largely perceive the Sun as female. [3] Bila is said to be a cannibal, roasting her victims over a fire, the origin of sunlight.
To prove this result, we will start by proving a simpler one. Replacing A and C with the identity matrix I, we obtain another identity which is a bit simpler: (+) = (+). To recover the original equation from this reduced identity, replace by and by .
Shoelace scheme for determining the area of a polygon with point coordinates (,),..., (,). The shoelace formula, also known as Gauss's area formula and the surveyor's formula, [1] is a mathematical algorithm to determine the area of a simple polygon whose vertices are described by their Cartesian coordinates in the plane.
