Early trigonometry The ancient Egyptians and Babylonians had known of theorems on the ratios of the sides of similar triangles for many centuries. But pre-Hellenic societies lacked the concept of an angle measure and consequently‚ the sides of triangles were studied instead‚ a field that would be better called "trilaterometry".[6]The Babylonian astronomers kept detailed records on the rising and setting of stars‚ the motion of the planets‚ and the solar and lunar eclipses‚ all of which required

mathematics and philosophy in a deeper way. One of the many names residing from Ancient Greece was Pythagoras a mathematical philosopher‚ who changed our present day apprehension of geometry with his astonishing creation of the theorem named after his name. The Pythagoras Theorem What is Philosophy in Mathematics? Mathematical philosophy is linked with the philosophical foundations and assumptions of mathematics. E.g. was calculus invented or rather discovered‚ how are theories justified. The final goal

trigonometric functions in current use were known in Islamic mathematics by the 9th century‚ as was the law of sines‚ used in solving triangles. Al-Khwārizmī produced tables of sines‚ cosines and tangents. They were studied by authors including Omar Khayyám‚ Bhāskara II‚ Nasir al-Din al-Tusi‚ Jamshīd al-Kāshī (14th century)‚ Ulugh Beg (14th century)‚ Regiomontanus (1464)‚ Rheticus‚ and Rheticus’ student Valentinus Otho. Madhava of Sangamagrama (c. 1400) made early strides in the analysis of trigonometric functions

period in which Pythagoras graced his presence on Earth happened so long ago that research on Pythagoras and his mathematical concept were not documented. This is important because many researchers argue if Pythagoras really came up with the Pythagorean Theorem or if it was just a legend or Greek story. After researching this topic‚ I have found that Pythagoras was more than just a “Greek story”. Pythagoras was born in the Samos Islands of Samos. Samos is a Greek island that is found beside the

(by mohan arora) Have you ever thought how this world of mathematics would be without irrational numbers? If the great Pythagorean hyppasus or any other mathematician would have not ever thought of such numbers? Before ‚understanding the development of irrational numbers ‚we should understand what these numbers originally are and who discovered them? In mathematics‚ an irrational number is any real number that cannot be expressed as a ratio a/b‚ where a and b are integers and b is non-zero

triangle has the same measure as the corresponding angle in the other triangle. The corresponding sides of similar triangles have lengths that are in the same proportion‚ and this property is also sufficient to establish similarity. A few basic theorems about similar triangles: * If two corresponding internal angles of two triangles have the same measure‚ the triangles are similar. * If two corresponding sides of two triangles are in proportion‚ and their included angles have the same measure

In today’s world‚ there are a multitude of mathematical theorems and formulas. One theorem that is particularly renowned is the Pythagorean Theorem. The theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides of any right triangle. While most people have heard of or even used the Pythagorean Theorem‚ many know little of the man who proved it. Pythagoras was born in 570 BC in Samos‚ Greece. His father‚ Mnesarchus‚ was a merchant from Tyre who traveled

Bhaskara II is a well-known mathematician of ancient India. He was born in 1114 AD in Vijayapura‚ India. Bhaskara II is also known as Bhaskaracharya‚ which means "Bhaskara the Teacher". His father Mahesvara was as an astrologer‚ who taught him mathematics‚ which he later passed on to his son Loksamudra. Bhaskara II was the head of the astronomical observatory at Ujjain‚ the chief mathematical center of ancient India. It goes to the credit of Varahamihira and Brahmagupta‚ the leading mathematicians

. Exercise: Week Six Concept Check The theorem works In any right triangle. A key observation is that a and b are at right angles. Movement in one direction has no impact on the other. The Pythagorean Theorem can be used with any shape and for any formula that squares a number. The Pythagorean Theorem lets you use find the shortest path distance between orthogonal directions. So it’s not really about right triangles — it’s about comparing “things” moving at right angles. The

Contribution of India in mathematics The most fundamental contribution of India in mathematics is the invention of decimal system of enumeration‚ including the invention of zero. The decimal system uses nine digits (1 to 9) and the symbol zero (for nothing) to denote all natural numbers by assigning a place value to the digits. The Arabs carried this system to Africa and Europe. 1) Aryabhata is the first well known Indian mathematician. Born in Kerala‚ he completed his studies at the university
