Precisely the the theory of Elliptic integrals was developed to calculate this arc length There are no closed form for this arc length in terms of elementary functions, we need especial functions Recall the coordinates at any point on the ellipse $$ \frac{x^2}{a^2} \frac{y^2}{b^2} = 1 \tag{1} $$ ParametricallyAnother way to look at it is this if we took a segment of length r (the radius) and molded it onto the circle, the angle formed by the radii connecting the center of the circle to the endpoints of the arc would have a measure of 1 radian As it turns out, one radian is equal to approximately 573°2 3) to (2;
