Spherical trigonometry is a subdivision of spherical geometry which studies the relationship between trigonometric functions of the sides and angles of the spherical triangles which is a part of the great circle of a sphere. The cross-section of a sphere is a hemisphere and the plane passing through the centre is a circle, called the […]
“……Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line,…..” Benoit Mandelbrot Then how can we define all these? We can’t explain these using Euclidean geometry. Fractal geometry is a new branch of mathematics which makes math more interesting than the […]
The Steinmetz solid (mouhefanggai or bicylinder) is the solid common to two (or three) right circular cylinders of equal radius intersecting at right angle is called the Steinmetz solid where each of the curves of the intersection of two cylinders is an ellipse. Mouhefanggai in Chinese language means “two square umbrellas”.Three intersecting cylinders are called […]
Logarithmic functions are the inverses of exponential functions, and any exponential function can be expressed in logarithmic form. Similarly, all logarithmic functions can be rewritten in exponential form. Logarithms are really useful in permitting us to work with very large numbers while manipulating numbers of a much more manageable size. Logarithms were introduced by John Napier […]
In mathematics, pi is the ratio of circumference to the diameter of a circle. symbol π was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by the Swiss mathematician Leonhard Euler. A pi is an irrational number and it is non-repeating. The pi value up to the first 100 […]
The Fibonacci series is a series formed by the Fibonacci numbers.The numbers in this series are given as 0, 1, 1, 2, 3, 5, 8, 13, 21, 38, . . . This series is named after a renowned mathematician Leonardo Pisano Bogollo, later known as Fibonacci. In a Fibonacci series, every term is the sum […]
