2. Turn (angle) - Wikipedia

   en.wikipedia.org/wiki/Turn_(angle)

   The turn (symbol tr or pla) is a unit of plane angle measurement that is the measure of a complete angle—the angle subtended by a complete circle at its center. One turn is equal to 2π radians, 360 degrees or 400 gradians. As an angular unit, one turn also corresponds to one cycle (symbol cyc or c) [1] or to one revolution (symbol rev or r). [2]

3. Glossary of mathematical jargon - Wikipedia

   The language of mathematics has a wide vocabulary of specialist and technical terms. It also has a certain amount of jargon: commonly used phrases which are part of the culture of mathematics, rather than of the subject.

4. List of logic symbols - Wikipedia

   en.wikipedia.org/wiki/List_of_logic_symbols

   In logic, a set of symbols is commonly used to express logical representation. The following table lists many common symbols, together with their name, how they should be read out loud, and the related field of mathematics.

5. Rotation (mathematics) - Wikipedia

   en.wikipedia.org/wiki/Rotation_(mathematics)

   Rotation can have a sign (as in the sign of an angle): a clockwise rotation is a negative magnitude so a counterclockwise turn has a positive magnitude. A rotation is different from other types of motions: translations , which have no fixed points, and (hyperplane) reflections , each of them having an entire ( n − 1) -dimensional flat of ...

   Lowercase ɐ (in Roman or two story form) is used in the International Phonetic Alphabet to identify the near-open central vowel.This is not to be confused with the turned alpha or turned script a, ɒ, which is used in the IPA for the open back rounded vowel.

   In other words, there exists a real number M such that | | for all x in X. A function that is not bounded is said to be unbounded. Sometimes, if f(x) ≤ A for all x in X, then the function is said to be bounded above by A. On the other hand, if f(x) ≥ B for all x in X, then the function is said to be bounded below by B.
