If r is the radius of the inscribed circle, then the circle is divided into three triangles with the same altitude r by the bisectors of the angles, so the area becomes S = r(a + b + c)/2 = rs. For x - y, we simply use the fact that sin (-y) = sin y and cos (-y) = cos y. That's practically a definition of mathematics: the study of structures and patterns in large numerical sets. Includes 20 sided, 12 sided, 10 sided, 8 sided, 6 sided and 4 sided dice.

To prove this theorem just let y = b sin q and x = b cos q and use the distance formula. A mathematical identity (as defined by the Merriam-Webster's Dictionary - www.m-w.com) is an equation that is satisfied by all values of the symbol. Both scripts had numeral symbols and numeral systems, which were initially not based on a place-value system. [48] The earliest surviving evidence of decimal place value numerals in India and southeast Asia is from the middle of the first millennium CE. [49] A copper plate from Gujarat, India mentions the date 595 CE, written in a decimal place value notation, although there is some doubt as to the authenticity of the plate. [49] Decimal numerals recording the years 683 CE have also been found in stone inscriptions in Indonesia and Cambodia, where Indian cultural influence was substantial. [49] There are older textual sources, although the extant manuscript copies of these texts are from much later dates. [50] Probably the earliest such source is the work of the Buddhist philosopher Vasumitra dated likely to the 1st century CE. [50] Discussing the counting pits of merchants, Vasumitra remarks, "When [the same] clay counting-piece is in the place of units, it is denoted as one, when in hundreds, one hundred." [50] Although such references seem to imply that his readers had knowledge of a decimal place value representation, the "brevity of their allusions and the ambiguity of their dates, however, do not solidly establish the chronology of the development of this concept." [50] A third decimal representation was employed in a verse composition technique, later labelled Bhuta-sankhya (literally, "object numbers") used by early Sanskrit authors of technical books. [51] Since many early technical works were composed in verse, numbers were often represented by objects in the natural or religious world that correspondence to them; this allowed a many-to-one correspondence for each number and made verse composition easier. [51] According to Plofker 2009, the number 4, for example, could be represented by the word " Veda " (since there were four of these religious texts), the number 32 by the word "teeth" (since a full set consists of 32), and the number 1 by "moon" (since there is only one moon). [51] So, Veda/teeth/moon would correspond to the decimal numeral 1324, as the convention for numbers was to enumerate their digits from right to left. [51] The earliest reference employing object numbers is a ca. 269 CE Sanskrit text, Yavanajātaka (literally "Greek horoscopy") of Sphujidhvaja, a versification of an earlier (ca. 150 CE) Indian prose adaptation of a lost work of Hellenistic astrology. [52] Such use seems to make the case that by the mid-3rd century CE, the decimal place value system was familiar, at least to readers of astronomical and astrological texts in India. [51] It has been hypothesized that the Indian decimal place value system was based on the symbols used on Chinese counting boards from as early as the middle of the first millennium BCE. [53] According to Plofker 2009, These counting boards, like the Indian counting pits, ..., had a decimal place value structure ...

The math answers are generated and displayed real-time, at the moment a web user types in their math problem and clicks "solve." The reciprocals of these functions are named the cosecant (csc or cosec), secant (sec), and cotangent (cot), respectively: The inverse functions are called the arcsine, arccosine, and arctangent, respectively.
