Let P (x, y) be any point on a curve y = ƒ(x). Let s denote the arc length measured from a fixed point A on the curve to the point P i.e. arc AP = s. Suppose that s increases as x increases. Clearly s is a function of x. We take a neighbouring point Q (x + Δx, y + Δy). Let AQ = s + Δs ∴ Arc PQ = Δs We shall assume that from the right-angled ΔPQN, we have Taking the limit as QP (or Δx0), we get Services: - Arc Length Derivative Homework | Arc Length Derivative Homework Help | Arc Length Derivative Homework Help Services | Live Arc Length Derivative Homework Help | Arc Length Derivative Homework Tutors | Online Arc Length Derivative Homework Help | Arc Length Derivative Tutors | Online Arc Length Derivative Tutors | Arc Length Derivative Homework Services | Arc Length Derivative
