The user may choose to replace the inclination angle by its complement, the elevation angle (or altitude angle), measured upward between the reference plane and the radial line—i.e., from the reference plane upward (towards to the positive z-axis) to the radial line. The depression angle is the negative of the elevation angle.
In emulation learning, subjects learn about parts of their environment and use this to achieve their own goals and is an observational learning mechanism (sometimes called social learning mechanisms). [1] In this context, emulation was first coined by child psychologist David Wood in 1988. [2]
The golden angle is the angle subtended by the smaller (red) arc when two arcs that make up a circle are in the golden ratio. In geometry, the golden angle is the smaller of the two angles created by sectioning the circumference of a circle according to the golden ratio; that is, into two arcs such that the ratio of the length of the smaller arc to the length of the larger arc is the same as ...
Determining the angle of the Earth's magnetic field with respect to the horizontal plane. Showing a deviation from the true vertical or horizontal. Surveying, to measure an angle of inclination or elevation. Alerting an equipment operator that it may tip over. Measuring angles of elevation, slope, or incline, e.g. of an embankment.
In computer graphics and geography, the angle of incidence is also known as the illumination angle of a surface with a light source, such as the Earth's surface and the Sun. [1] It can also be equivalently described as the angle between the tangent plane of the surface and another plane at right angles to the light rays. [ 2 ]
All positions on the eye-level line except the point of tangency are outside of the circle, and therefore the angle subtended by the painting from those points is smaller. The point of tangency can be constructed by the following steps: [4] [5] Reflect the bottom point of the painting across the line at eye-level.
Geometry has two great treasures: one is the theorem of Pythagoras, the other the division of a line into extreme and mean ratio. The first we may compare to a mass of gold, the second we may call a precious jewel. [2] However, Kepler was not the first to describe this triangle. [3] Kepler himself credited it to "a music professor named Magirus ...
