With further aid of half-angle formulae and pythagorean identities the chord length is c 2 R sin th 2 R 2 2 cos th 2 R 1 d R 2 displaystyle c2Rsin frac theta 2Rsqrt 2-2cos theta 2Rsqrt 1-dR2.
The infinite line extension of a chord is a secant line or just secantMore generally a chord is a line segment joining two points on any curve for instance an ellipseA chord that passes through a circles center point is the circles diameterThe word chord is from the Latin chorda meaning bowstring. So the length of the chord is approximately 131 cm. Sharpness of circular curve. Using the formula half of the chord length should be the radius of the circle times the sine of half the angle.
