To calculate the exact length of the spiral, we write the equation of the curve in polar coordinates: Here is the distance between the axis as a function of the angle . This calculator calculates the deflection angle to any point on the curve (i) using length of spiral from tangent to any point (l), length of spiral (ls), radius of simple curve (r) values. For example, we could choose to set the Polynomial Order to be 4: This results in the following curve: The equation of the curve is as follows: y = -0.0192x4 + 0.7081x3 8.3649x2 + 35.823x 26.516. For a spiral curve L is the same as the length of the spiral. The calculation is an expansion of Fresnel integrals.
