Calculator to compute the arc length of a curve. Specify a curve in polar coordinates or parametrically. Compute arc length in arbitrarily many dimensions.
The formula for arc length in polar coordinates is given by the integral $$ L = \int_{\theta_1}^{\theta_2} \sqrt{ \left( \frac{dr}{d\theta} \right)^2 + r^2 } \, d\theta $$. When calculating arc length, 'r' represents the radius as a function of the angle 'θ', and 'dr/dθ' is its derivative with respect to 'θ'.
16 Νοε 2022 · In this section we will discuss how to find the arc length of a polar curve using only polar coordinates (rather than converting to Cartesian coordinates and using standard Calculus techniques).
In rectangular coordinates, the arc length of a parameterized curve (x(t), y(t)) for a ≤ t ≤ b is given by. L = ∫b a√(dx dt)2 + (dy dt)2dt. In polar coordinates we define the curve by the equation r = f(θ), where α ≤ θ ≤ β. In order to adapt the arc length formula for a polar curve, we use the equations.
