WebLet these equations describe a curve C that is continuous for all t ∈ [ a.. b] and continuously differentiable for all t ∈ ( a.. b) . Suppose that the graph of the curve does not intersect itself for any t ∈ ( a.. b) . Then the arc length of C between a and b is given by: s = ∫ a b ( d x d t) 2 + ( d y d t) 2 d t. for d x d t ≠ 0 . WebArc Length in Rectangular Coordinates. Let a curve C be defined by the equation y = f (x) where f is continuous on an interval [a, b]. We will assume that the derivative f '(x) is also continuous on [a, b]. Figure 1. The length of the curve from to is given by. If we use Leibniz notation for derivatives, the arc length is expressed by the formula.
