We can find the arc length l of a polar curve r = r(θ) from θ = a to θ = b by. Use a graph to determine the parameter interval. Y = x − x2 + sin−1 x.
Y =√X − X2 + Sin−1√X.
The polar equation is expressed in terms of a periodic function, so we have to know its period to get the exact length (and not just a portion or some excess of it). Note that the sin ( π / 12) we get as a component. Arc length of 2d parametric curve.

R = 𝜃 2, 0 ≤ 𝜃 ≤ 5𝜋. Use a graph to determine the parameter interval. The length of the polar curve is given by ∫b a √(r2 +(dr dθ)2)dθ ∫ a b ( r 2 + ( d r d θ) 2) d θ.
Where We Also Assume That The Curve Is Traced Out.
Given, r = θ, 0 ≤ θ ≤ π/2. L = ∫ b a √r2 +(dr dθ)2dθ l = ∫ a b r 2 + ( d r d θ) 2 d θ. The exact length of the polar curve.
