In mathematics, sine and cosine are trigonometric functions of an angle.The sine and cosine of an acute angle are defined in the context of a right triangle: for the specified angle, its sine is the ratio of the length of the side that is opposite that angle to the length of the longest side of the triangle (the hypotenuse), and the cosine is the ratio of the length of the adjacent leg to that ...
The first way to divide sentences into groups in Ancient Greek was the original παράγραφος [parágraphos], which was a horizontal line in the margin to the left of the main text. [7] As the paragraphos became more popular, the horizontal line eventually changed into the Greek letter Gamma ( Γ , γ ) and later into litterae ...
The scientific study of probability is a modern development of mathematics. Gambling shows that there has been an interest in quantifying the ideas of probability throughout history, but exact mathematical descriptions arose much later. There are reasons for the slow development of the mathematics of probability.
The idea of the expected value originated in the middle of the 17th century from the study of the so-called problem of points, which seeks to divide the stakes in a fair way between two players, who have to end their game before it is properly finished. [4] This problem had been debated for centuries.
Suppose we wish to determine whether n = 221 is prime.Randomly pick 1 < a < 220, say a = 38.We check the above congruence and find that it holds: = (). Either 221 is prime, or 38 is a Fermat liar, so we take another a, say 24:

In the state, the rate of population growth is India's lowest, and the decadal growth of 4.9% in 2011 is less than one-third of the all-India average of 17.6%. [339] Kerala's population more than doubled between 1951 and 1991 by adding 15.6 million people to reach 29.1 million residents in 1991; the population stood at 33.3 million by 2011. [339]
