  2. 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]

    When timetables are constructed by hand, the process is often 10% mathematics and 90% politics, [2] leading to errors, inefficiencies, and resentment among teachers and students." [1] For the simplest school timetable, such as an elementary school, these conditions must be satisfied: [3] a teacher cannot teach two courses in the same time slot

  5. Degree (angle) - Wikipedia

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

    A chart to convert between degrees and radians. In most mathematical work beyond practical geometry, angles are typically measured in radians rather than degrees. This is for a variety of reasons; for example, the trigonometric functions have simpler and more "natural" properties when their arguments are expressed in radians. These ...

  9. Grade (slope) - Wikipedia

    en.wikipedia.org/wiki/Grade_(slope)

    Grade is usually expressed as a percentage, but this is easily converted to the angle α by taking the inverse tangent of the standard mathematical slope, which is rise / run or the grade / 100. If one looks at red numbers on the chart specifying grade, one can see the quirkiness of using the grade to specify slope; the numbers go from 0 for ...
