The chord function is defined geometrically as shown in the picture. The chord of an angle is the length of the chord between two points on a unit circle separated by that central angle. The angle θ is taken in the positive sense and must lie in the interval 0 < θ ≤ π (radian measure). See more A chord of a circle is a straight line segment whose endpoints both lie on a circular arc. If a chord were to be extended infinitely on both directions into a line, the object is a secant line.

WebSep 3, 2024 · 1. I think there's no elementary formula for this. Denote arc and chord as a, b, then r θ = a, 2 r sin ( θ / 2) = b. Divide the first equation by the second, we get. θ 2 sin ( θ / 2) = a b θ = 2 a b sin ( θ / 2). Subsitute θ / 2 with u, we get. u = a b sin u. which is an equation you can't give simple solution to.
