Arc length in polar coordinates
I know that an arc length in polar coordinates can be computed by integrating $$int ds$$ using the formula ##ds=sqrt{rho^2 + frac{dr}{dtheta}^2}dtheta##. But, seeing that ##s=rhotheta## and ##ds = rho dtheta##, why is it wrong to calculate arc lengths with this expression for ##ds##?
