Unit of angular measurement equal to the angle at the center of a circle subtended by an arc equal in length to the radius. One radian equals about 57.296 degrees. Useful for figuring out the pixel resolutions of spacecraft images. Multiply a camera's angular resolution in radians by its distance from a target and you get the width of one pixel, the pixel scale.
The natural unit of measure of the angle between two intersecting half-lines on the angles from one half-line to another intersecting half-line. It is the angle subtended by an arc of a circle equal in length to the radius of the circle. As the circumference of a circle is equal to 2Ï€ times its radius, the number of radians in an angle of 360Â° or in a complete turn is 2Ï€.
A unit of angular measurement. There are 2p radians in a circle. Therefore 1 radian = 57.3 degrees. Range: The distance from the front bumper of the following vehicle to the rear bumper of the lead vehicle. For this report, this is the distance from the SV to the slow lead vehicle in the same lane or to the closest forward vehicle in the destination lane, or the distance from the front bumper of the closest rear vehicle in the adjacent lane to the rear bumper of the SV, along a longitudinal axis through either of the vehicles.
The supplementary SI unit of angular measure, defined as the central angle of a circle whose subtended arc is equal to the radius of the circle. One radian is approximately 57o. There are two pi radians in a circle.
a unit of angle measure defined as the measure of an angle whose intercepted arc is equal to the radius of the circle when the angle's vertex is positioned at the center of the circle. Consequently, 2Ï€ radians = 360Â° and thus one radian is 180/Ï€ degrees or approx. 57.3Â°. The unit of radians is most typically used in trigonometry and frequently the unit is omitted such that the value of the angle's measure is, by convention, merely understood to be radians ( i.e., in the absence of any other indicated unit such as degrees, minutes, and/or seconds)...
A radian is a unit of angular measure that is equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle. A radian is about 57.2957° (1 degree = 0.0174532 radians). There are 2*pi radians in 360°.
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.
Mathematics. A unit of angular measure equal to the angle subtended at the center of a circle by an arc equal in length to the radius of the circle, approximately 57°17'44.6 Filters. Frequency is measured in radians/second. One cycle (360°) equals 2 pi radians.
The radian is the SI unit for angular measure. One radian is equal to the angle at the center of a circle made by a slice of that circle in which the distance around the circumference is equal to the radius of the circle (one arc length). One complete circle equals 2Ï€ radians. For more information, see Radian at the Wikipedia. Radian image courtesy of Wikipedia.
A natural unit of angular measurement equal to 57.29578 degrees of arc. Note that 2pi radians = 360 degrees and 2pi f = angular frequency in radians per second (represented by the Greek letter omega), where f = frequency in Hz.
