2. Degree (angle) - Wikipedia

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

   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 in which one full rotation is 360 degrees. [4] It is not an SI unit—the SI unit of angular measure is the radian—but it is mentioned in the SI brochure as an accepted unit. [5]

3. Gradian - Wikipedia

   en.wikipedia.org/wiki/Gradian

   [18] [19] Today, the degree, ⁠ 1 / 360 ⁠ of a turn, or the mathematically more convenient radian, ⁠ 1 / 2 π ⁠ of a turn (used in the SI system of units) is generally used instead. In the 1970s – 1990s, most scientific calculators offered the gon (gradian), as well as radians and degrees, for their trigonometric functions . [ 23 ]

4. Angle - Wikipedia

   en.wikipedia.org/wiki/Angle

   It is denoted by a double prime ( ″ ). For example, 3° 7′ 30″ is equal to 3 + ⁠ 7 / 60 ⁠ + ⁠ 30 / 3600 ⁠ degrees, or 3.125 degrees. The arcsecond is the angle used to measure a parsec: grad: 400: 0°54′ The grad, also called grade, gradian, or gon. It is a decimal subunit of the quadrant. A right angle is 100 grads.

5. Turn (angle) - Wikipedia

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

   Many angle units are defined as a division of the turn. For example, the degree is defined such that one turn is 360 degrees. Using metric prefixes, the turn can be divided in 100 centiturns or 1000 milliturns, with each milliturn corresponding to an angle of 0.36°, which can also be written as 21′ 36″.

6. Circle - Wikipedia

   en.wikipedia.org/wiki/Circle

   The angle subtended by a complete circle at its centre is a complete angle, which measures 2 π radians, 360 degrees, or one turn. Using radians, the formula for the arc length s of a circular arc of radius r and subtending a central angle of measure 𝜃 is s = θ r , {\displaystyle s=\theta r,}

7. Plate trick - Wikipedia

   en.wikipedia.org/wiki/Plate_trick

   In mathematics and physics, the plate trick, also known as Dirac's string trick (after Paul Dirac, who introduced and popularized it), [1] [2] the belt trick, or the Balinese cup trick (it appears in the Balinese candle dance), is any of several demonstrations of the idea that rotating an object with strings attached to it by 360 degrees does not return the system to its original state, while ...

9. Exact trigonometric values - Wikipedia

   en.wikipedia.org/wiki/Exact_trigonometric_values

   In mathematics, the values of the trigonometric functions can be expressed approximately, as in ⁡ (/), or exactly, as in ⁡ (/) = /. While trigonometric tables contain many approximate values, the exact values for certain angles can be expressed by a combination of arithmetic operations and square roots .
