  2. Regiomontanus' angle maximization problem - Wikipedia

    en.wikipedia.org/wiki/Regiomontanus'_angle...

    In mathematics, the Regiomontanus's angle maximization problem, is a famous optimization problem [1] posed by the 15th-century German mathematician Johannes Müller [2] (also known as Regiomontanus). The problem is as follows: The two dots at eye level are possible locations of the viewer's eye. A painting hangs from a wall.

  3. Mountain climbing problem - Wikipedia

    en.wikipedia.org/wiki/Mountain_climbing_problem

    A trivial example. In mathematics, the mountain climbing problem is a mathematical problem that considers a two-dimensional mountain range (represented as a continuous function), and asks whether it is possible for two mountain climbers starting at sea level on the left and right sides of the mountain to meet at the summit, while maintaining equal altitudes at all times.

  4. Seked - Wikipedia

    en.wikipedia.org/wiki/Seked

    The most famous example of a seked slope is of the Great Pyramid of Giza in Egypt built around 2550 BC. Based on modern surveys, the faces of this monument had a seked of ⁠5 + 1 / 2 ⁠ , or 5 palms and 2 digits, in modern terms equivalent to a slope of 1.27, a gradient of 127%, and an elevation of 51.84° from the horizontal (in our 360 ...

  5. Euler angles - Wikipedia

    en.wikipedia.org/wiki/Euler_angles

    The Euler angles are three angles introduced by Leonhard Euler to describe the orientation of a rigid body with respect to a fixed coordinate system. [ 1 ] They can also represent the orientation of a mobile frame of reference in physics or the orientation of a general basis in three dimensional linear algebra .

  6. Grade (slope) - Wikipedia

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

    α = angle of inclination. The grade (US) or gradient (UK) (also called stepth, slope, incline, mainfall, pitch or rise) of a physical feature, landform or constructed line is either the elevation angle of that surface to the horizontal or its tangent. It is a special case of the slope, where zero indicates horizontality. A larger number ...

  7. Angle of climb - Wikipedia

    en.wikipedia.org/wiki/Angle_of_Climb

    The angle of climb can be defined as the angle between a horizontal plane representing the Earth's surface, and the actual flight path followed by the aircraft during its ascent. The speed of an aircraft type at which the angle of climb is largest is called V X. It is always slower than V Y, the speed for the best rate of climb. As the latter ...

  8. Rifleman's rule - Wikipedia

    en.wikipedia.org/wiki/Rifleman's_rule

    Adjust the bore angle by the angle correction. The gun sight is adjusted up by 0.94 mil or 3.2' in order to compensate for the bullet drop. The gunsights are usually adjustable in unit of 1 ⁄ 2 minutes, 1 ⁄ 4 minutes of angle or 0.1 milliradians .

  9. Langley's Adventitious Angles - Wikipedia

    en.wikipedia.org/wiki/Langley's_Adventitious_Angles

    The problem of calculating angle is a standard application of Hansen's resection. Such calculations can establish that ∠ B E F {\displaystyle \angle {BEF}} is within any desired precision of 30 ∘ {\displaystyle 30^{\circ }} , but being of only finite precision, always leave doubt about the exact value.
