Parametric length formula
WebThe answer is 6√3. The arclength of a parametric curve can be found using the formula: L = ∫ tf ti √( dx dt)2 + (dy dt)2 dt. Since x and y are perpendicular, it's not difficult to see why this computes the arclength. It isn't very different from the arclength of a regular function: L = ∫ b a √1 + ( dy dx)2 dx. WebNov 16, 2024 · In other words, the exact length will be, L = lim n→∞ n ∑ i=1 P i−1 P i L = lim n → ∞ ∑ i = 1 n P i − 1 P i . Now, let’s get a better grasp on the length of each of these …
