Finding central angle formula

WebThe degree of curvature is defined as the central angle to the ends of an agreed length of either an arc or a chord; [1] various lengths are commonly used in different areas of practice. This angle is also the change in forward direction as that portion of the curve is traveled. In an n -degree curve, the forward bearing changes by n degrees ... WebThe Earth is nearly spherical, so great-circle distance formulas give the distance between points on the surface of the Earth correct to within about 0.5%. The vertex is the highest-latitude point on a great circle. Formulae An illustration of the central angle, Δσ, between two points, P and Q. λ and φ are the longitudinal and latitudinal ...
