Eccentricity

Eccentricity can be defined as how much a conic section deviates from being circular. A circle has an eccentricity of 0, this means that eccentricity shows how un-circular a curve is. Higher the eccentricity, lesser the curve. Eccentricity of different curves: A circle has an eccentricity of

Octahedron

An octahedron is a geometrical shape which has 8 faces, twelve edges and six vertices. Examples include boat, heptagonal pyramid, hexagonal prism etc. The 8 faces of the octahedron is triangular in shape. Area of Octahedron If (r) is the distance from the center to one vertex.

Prime Number

A prime number is a whole number which is greater than 1 and is not created by multiplying other whole numbers. Its factors are 1 and the number itself. Numbers which have more than two factors are known as composite numbers. Some of the first prime numbers

Spheroid

A spheroid is three dimensional shape which looks like a flattened sphere having circular symmetry. A spheroid is formed when an ellipse is rotated about one of its principal axis. An ellipse has two principal axes major axis and minor axis. When the ellipse is rotated about

Geometric Progression

Geometric progression is also known as geometric sequence. It is a sequence of numbers which differ from each other by a common ratio. The sequence works in a manner such that any element or number after the first is obtained by multiplying the preceding element common ratio.
