polar angle may be called inclination angle, zenith angle, normal angle, or the colatitude. The user may choose to ignore the inclination angle and use...

origin increases; φ ^ {\displaystyle {\boldsymbol {\hat {\varphi }}}} , the direction in which the angle in the x-y plane counterclockwise from the positive...

pair of flats in a Euclidean space of arbitrary dimension one can define a set of mutual angles which are invariant under isometric transformation of the...

an angle from the periapsis. The mean anomaly M is a mathematically convenient fictitious "angle" which does not correspond to a real geometric angle...

of ordered set notation) and matrices. The angle may be prefixed with the angle symbol ( ∠ {\displaystyle \angle } ); the distance-angle-distance combination...

points. As shown in the diagram, x ^ 1 {\displaystyle {\hat {\mathbf {x} }}_{1}} is at angle γ 1 {\displaystyle \gamma _{1}} with respect to its beginning...

providing a straightedge at a right angle or other particular planar angle to a baseline. The simplest form of set square is a triangular piece of transparent...

rotation axis ( ω ^ = Z ^ {\displaystyle {\hat {\omega }}={\hat {Z}}} , in the geocentric coordinate system). If angle is measured in radians, the linear velocity...

under a set of transformations. These transformations can cause the displacement of the triangle in the plane, while leaving the vertex angle and the...

{\displaystyle {\hat {\mathbf {u} }}_{\theta }(t)} is a unit vector and its tip traces a unit circle with an angle that is π/2 + θ. Hence, an increase in angle dθ by...

point on a plane is determined by a distance from a reference point and an angle from a reference direction. The reference point (analogous to the origin...
