Arc length is the distance between two points along a section of a curve. Development of a formulation of arc length suitable for applications to mathematics

If the length of an arc is exactly half of the circle, it is known as a semicircular arc. The length (more precisely, arc length) of an arc of a circle

defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth's circumference is very near 21600 nmi. A minute of arc is ⁠π/10800⁠

various quantities associated with them, such as the curvature and the arc length, are expressed via derivatives and integrals using vector calculus. One

function of the parameter s. (The parameter may be thought as time or as arc length from a given origin.) Let T(s) be a unit tangent vector of the curve at

chord length and height are given or measured, and sometimes the arc length as part of the perimeter, and the unknowns are area and sometimes arc length. These

diagram, θ is the central angle, r the radius of the circle, and L is the arc length of the minor sector. A sector with the central angle of 180° is called

defined as the central angle to the ends of an agreed length of either an arc or a chord; various lengths are commonly used in different areas of practice

\sin \theta )=(b\,\theta \,\cos \theta ,b\,\theta \,\sin \theta )} the arc length from θ1 to θ2 is b 2 [ θ 1 + θ 2 + ln ⁡ ( θ + 1 + θ 2 ) ] θ 1 θ 2 {\displaystyle
