This is the arc length formula when the angle is in degrees. The length of an arc can be calculated using different formulas, based on the unit of the central angle of the arc. The measurements of the central angle can be given indegreesorradians, and accordingly, we calculate the arc l...

What is the formula for the length of an arc? If the subtended angle is given in radians, the formula for arc length is s=r*theta, where "s" is the arc length, "r" is the radius of the circle, and "theta" is the subtended angle. If the angle is instead given in degrees, the...
We use Taylor's formula with Lagrange remainder to prove that functions with bounded second derivative are rectifiable in the case when polygonal paths are defined by interval subdivisions which are equally spaced. As a means for generating interesting examples of exact arc length calculations in ...
