|---|---|
| tangential angle | In geometry, the tangential angle of a curve in the Cartesian plane, at a specific point, is the angle between the tangent line to the curve at the given point and the -axis. |
| subtended angle | In geometry, an angle is subtended by an arc, line segment, or any other section of a curve when its two rays pass through the endpoints of that arc, line segment, or curve section. |
| polar coordinate system | In mathematics, the polar coordinate system is a two-dimensional coordinate system in which each point on a plane is determined by a distance from a reference point and an angle from a reference direction. |
| anglenoun | (geometry) A figure formed by two rays which start from a common point (a plane angle) or by three planes that intersect (a solid angle). |
| radiannoun | (geometry) In the International System of Units, the derived unit of plane angle: the angle subtended at the centre of a circle by an arc of its circumference equal in length to the radius of the circle. |
| distance from a point to a plane | In Euclidean space, the distance from a point to a plane is the distance between a given point and its orthogonal projection on the plane, the perpendicular distance to the nearest point on the plane. |
| argumentnoun | (countable, also figuratively) A fact or statement used to support a proposition; a reason. |
| radius vectornoun | (geometry) Of a point, a vector going from the origin to that point; equivalently, the transpose of the point. |
| polar coordinatesnoun | (mathematics) The coordinates of a point in a plane, measured as its Cartesian distance from the origin and the angle measured counterclockwise from the x-axis to a line joining the point to the origin. |
| spherical anglenoun | (geometry) A particular dihedral angle, the angle between two intersecting arcs on a sphere, measured by the angle between the planes containing the arcs. |
| radial function | In mathematics, a radial function is a real-valued function defined on a Euclidean space whose value at each point depends only on the distance between that point and the origin. |
| angle of rotation | — |
| euler's formulanoun | (complex analysis) A formula which links complex exponentiation with trigonometric functions: |
| center of curvaturenoun | US standard spelling of centre of curvature. [(mathematics, for any point on a curve) The centre of the osculating circle at the point on the curve.] |
| trigonometric functionnoun | (trigonometry) Any function of an angle expressible as the ratio of two of the sides of a right triangle that has that angle (e.g., sine), or that subtracts 1 from such a ratio or subtracts such a ratio from 1 (e.g., coversed sine). |
| plane anglenoun | (geometry) An angle formed by two intersecting straight lines. |
| sum of angles of a triangle | In a Euclidean space, the sum of angles of a triangle equals a straight angle (180 degrees, radians, two right angles, or a half-turn). |
| unit circlenoun | (trigonometry, the unit circle) The circle of radius 1 with centre at the origin, used in defining trigonometric functions. |
| altitudenoun | The absolute height of a location, usually measured from sea level. |
| direction cosine | In analytic geometry, the direction cosines (or directional cosines) of a vector are the cosines of the angles between the vector and the three positive coordinate axes. |
