Definition von radian im Englisch Englisch wörterbuch
In the International System of Units, the derived unit of plane angular measure of angle equal to the angle subtended at the centre of a circle by an arc of its circumference equal in length to the radius of the circle. Symbol: rad
A unit of plane angular measurement equal to the angle at the centre of a circle subtended by an arc equal in length to the radius Since the circumference of a circle is equal to 2p times its radius, the number of radians in an angle of 360 degrees or in a complete turn is 2p, so that 1 radian equals about 57 29 degrees
Unit of angular measure equal to 57 3°, the ratio of arc length to the radius of the circle
the unit of plane angle adopted under the Systeme International d'Unites; equal to the angle at the center of a circle subtended by an arc equal in length to the radius (approximately 57 295 degrees)
{i} central angle of an arc of any circle that is equal in length to the radius of the same circle (Mathematics)
The SI unit of plane angle One radian equals the angle subtended at the center of a circle by a circular arc which is equal in length to the radius of the circle
A unit of angular measurement The angle that, when placed with its vertex at the center of a circle, subtends on the circumference an arc equal in length to the radius of the circle Approximately 57 3o
A radian is a unit of angular measure equal to the angle subtended at the center of a circle by an arc of length equal to the radius of the circle equal to approximately 57 degrees, 17 minutes, 44 6 seconds
The angle subtended at the center of a circle by an arc equal in length to a radius of the circle It is equal to 360°/2π or approximately 57 degrees 17 minutes 44 8 seconds
A measure of angle; there are 2p radians in a circle The arc subtended by a radian is equal to the radius of the associated circle
A unit equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle
Equal to the central angle subtended by an arc of unit length at the centre of a circle of unit radius
A radian is a unit arc, each having a length equal to the length of the circle's radius To find the angle Ø, in radians of a circle is equal to the length of the circle circumference divided by the radius of that circle; Ø = l ÷ r, this is rotational motion The circumference of a circle whose radius has a length r is r * 2; thus Ø = l ÷ r = 2 * r ÷ r = 2 = approximately 6 2831853072 radians 1 rad = 360 ÷ 6 28318530717959 = 57 2957795130823º = 57º 17 7467707849372 min or 57º 17 min and 44 8062470962331 sec or approximately 57º 18 min To convert from degrees to radians is: Rad (angle) = degrees (angle) * ÷ 180
Official unit of angular measurment in the metric (SI) system PI radians (3 1415 ) = 180°
An arc in a circle, equal in length to the radius; an angle (57 3°) at the center of a circle, formed by 2 radii cutting off such an arc Thus one rad = 57 3°
A unit of angular measurement equal to the angle at the center of a circle subtended by an arc equal in length to the radius There are 2 pi radians in a circle
Standard unit of angle: the angle at which the arc of circle has the same length as the radius
An arc of a circle which is equal to the radius, or the angle measured by such an arc
A unit of measure for angles One radian is the angle subtended by an arc that has a curved length equal to the radius of the arc In other words, if you start with a circle, then take a line that has the same length as the radius of that circle and bend it around the circle's circumference, it will encompass an angle of one radian Since pi (3 1415926535 ) represents the ratio of a circle's circumference to its diameter, and its circumference encompasses 360°, pi also represents the ratio of a semicircle (180°) to its radius Therefore, 180° equals pi radians So, to convert radians to degrees, multiply radians by 57 29578 or (180/pi) To convert degrees to radians, multiply degrees by 0 017453293 or (pi/180)
A system for measuring angles wherein a full circle is 2 PI = 6 28 radians The system of measuring angles in radians is common in mathematics and science, though use of degrees is more common outside these fields Angles measured in radians are used to specify rotation angles A value in radians can be converted to degrees by this formula: degrees = radians * 180 0 / 3 142 [see degrees and rotation angle]
A measure of angles A full revolution corresponds to 2* (=6 28 ), half a revolution to , quarter revolution = /2 Correspondingly, 1 rad = 1/(2*) th of a full revolution Conversion to degrees : 1 rad = 180/ deg = 57 29578 deg
Convention for describing the size of an angle with respect to =3 141592 , rather than with respect to "degrees" Conversion between degrees and radians uses the equivalence
