54′. In trigonometry, the gradian – also known as the gon (from Ancient Greek γωνία (gōnía) 'angle'), grad, or grade[1] – is a unit of measurement of an angle, defined as one-hundredth of the right angle; in other words, 100 gradians is equal to 90 degrees. [2][3][4] It is equivalent to 1 400 of a turn, [5] 9 10 of ...
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]
I submitted an page move request for renaming gradian to Gon (angle) or Gon (angle measurement)), gon is the ISO unit (ISO 80000-3#Units of angle. Join the discussion at Talk:Gradian#Requested move 27 October 2015. I don't really care anyway, but it is a bit do we adhere to ISO standards. WillemienH 08:36, 27 October 2015 (UTC)
On a circle, a digon is a tessellation with two antipodal points, and two 180° arc edges. In geometry, a bigon, [1] digon, or a 2-gon, is a polygon with two sides (edges) and two vertices. Its construction is degenerate in a Euclidean plane because either the two sides would coincide or one or both would have to be curved; however, it can be ...
Gradian → – Gon is the name of this unit in ISO 31-1 (superseded by ISO 80000-3) and in ISO 80000-3 ISO 80000-3#Units of angle. Prefereably is even Gon (angle measurement) (. I think where possible it is best to follow ISO standards. WillemienH 08:25, 27 October 2015 (UTC) Probably oppose. I think ISO standards are at best a tiebreaker.
Gradient. The gradient, represented by the blue arrows, denotes the direction of greatest change of a scalar function. The values of the function are represented in greyscale and increase in value from white (low) to dark (high). In vector calculus, the gradient of a scalar-valued differentiable function of several variables is the vector field ...
Grade (slope) The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal. It is a special case of the slope, where zero indicates horizontality. A larger number indicates higher or steeper ...
The following outline is provided as an overview of and topical guide to trigonometry: Trigonometry – branch of mathematics that studies the relationships between the sides and the angles in triangles. Trigonometry defines the trigonometric functions, which describe those relationships and have applicability to cyclical phenomena, such as waves.
