WebSep 7, 2024 · To use the formula for curvature, it is first necessary to express ⇀ r(t) in terms of the arc-length parameter s, then find the unit tangent vector ⇀ T(s) for the function ⇀ r(s), then take the derivative of ⇀ T(s) with respect to s. This is a tedious process. Fortunately, there are equivalent formulas for curvature. WebA spiral curve can be used to provide a gradual transition between tangent sections and circular curves. While a circular curve has a radius that is constant, a spiral curve has a radius that varies along its length. The radius decreases from infinity at the tangent to the radius of the circular curve it is intended to meet.
