Table 1 Descriptions & number of Points of Circles at the Base of Stupa
The observation equation for the circle after linearizing using Taylor series and neglecting 2nd and higher orders is in the form of equation (3).
Due to the neglection of the second and higher orders of the Taylor series, results obtained by the above equations to be iterated until it reached to the specified tolerance levels.
Computation
A computer programme was specially developed to solve the above equations due to the complex nature of the calculation and the iterative process. Hence a computer programme was developed to execute the above calculations using FORTRAN77 scientific programming language. All calculations were carried out in double precision mode (up to sixteen decimal places) to maintain required accuracy.
