question: A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by (the degree symbol), is a measurement of a plane angle, defined so that a full rotation is 360 degrees.

It is not an SI unit, as the SI unit of angular measure is the radian, but it is mentioned in the SI brochure as an accepted unit. Because a full rotation equals 2 radians, one degree is equivalent to radians.

The original motivation for choosing the degree as a unit of rotations and angles is unknown. One theory states that it is related to the fact that 360 is approximately the number of days in a year. Ancient astronomers noticed that the sun, which follows through the ecliptic path over the course of the year, seems to advance in its path by approximately one degree each day. Some ancient calendars, such as the Persian calendar, used 360 days for a year. The use of a calendar with 360 days may be related to the use of sexagesimal numbers.

Another theory is that the Babylonians subdivided the circle using the angle of an equilateral triangle as the basic unit and further subdivided the latter into 60 parts following their sexagesimal numeric system. The earliest trigonometry, used by the Babylonian astronomers and their Greek successors, was based on chords of a circle. A chord of length equal to the radius made a natural base quantity. One sixtieth of this, using their standard sexagesimal divisions, was a degree.
1. How many degrees are in a full circle?
2. Is it an SI unit?
****
answer: 1. 360 degrees
2. no

The Encyclopedia of Mathematics (also EOM and formerly Encyclopaedia of Mathematics) is a large reference work in mathematics. It is available in book form and on CD-ROM.

The 2002 version contains more than 8,000 entries covering most areas of mathematics at a graduate level, and the presentation is technical in nature. The encyclopedia is edited by Michiel Hazewinkel and was published by Kluwer Academic Publishers until 2003, when Kluwer became part of Springer. The CD-ROM contains animations and three-dimensional objects.

The encyclopedia has been translated from the Soviet "Matematicheskaya entsiklopediya" (1977) originally edited by Ivan Matveevich Vinogradov and extended with comments and three supplements adding several thousand articles.

Until November 29, 2011, a static version of the encyclopedia could be browsed online free of charge online This URL now redirects to the new wiki incarnation of the EOM.

A new dynamic version of the encyclopedia is now available as a public wiki online. This new wiki is a collaboration between Springer and the European Mathematical Society. This new version of the encyclopedia includes the entire contents of the previous online version, but all entries can now be publicly updated to include the newest advancements in mathematics. All entries will be monitored for content accuracy by members of an editorial board selected by the European Mathematical Society. What are the answers to this following set of questions: 1. What EOM stands for?
2. What is it?
3. In how many formats it is available?
4. What are they?
5. Was a static version available?
6. Was it discontinued?
7. When?
8. Was it free?
9. What is the new version now?
10. How many organizations work together to make it possible?
11. What are they?
12. Can this be edited by public?

input: Make use of the article to answer the questions. Mabel's aunt wanted to give her the best birthday present ever. So the day after Mabel's birthday, her aunt brought her to the pet store! Mabel had been asking her aunt for a pet for a very long time. Many of her friends had pets, and she wanted one too. Her friend Faith had a hamster named Peaches. Bobby had a rat named Hugo! Melissa had two snakes and a lizard! Heather had a fish bowl with three fish. Mabel couldn't wait to get her pet and tell her friends all about it. At the pet store, Mabel and her aunt looked at all the animals they had. They saw puppies, kittens, fish, turtles, frogs, and bunnies. Mabel saw a cute black puppy that she thought she might like. There was also a white kitten with blue eyes. But then Mabel saw a gray bunny who was fluffy and soft, and she knew that she wanted the bunny as her pet. Her aunt helped her buy the bunny. They also got everything they needed for the bunny. They got a cage, a water bowl, and bunny food. Mabel named her new bunny Fluffy. Mabel thanked her aunt, and she had the best birthday ever! 1.
