We approximate a circular arc using a polynomial curve of degree 6. The approximation has least deviation from the x-axis and the error function is of degree 12; the error function equioscillates 13 times rather than the classical 8 times equioscillations that are mathematically guaranteed by the Borel and Chebyshev theorems without a method to find their approximation.
