WebFree Arc Length calculator - Find the arc length of functions between intervals step-by-step WebDec 19, 2024 · Step 1. The given function is. r = 8 + 8 cos θ on the interval 0 ≤ θ ≤ π. The length of the polar curve is given by. L = ∫ a b ( r ( θ)) 2 + ( r ′ ( θ)) 2 d θ. First, find the derivative: r ′ ( θ) ( 8 cos ( θ) + 8) ′ = − 8 sin ( θ) Step 2. Finally, calculate the integral.
