Q - What is the Western method ? A- The Western method is to find out the Mean Anomaly of the planet, then the true Anomaly and the add to it the Argument of Perihelion to get Theta ( Theta = v + w ). The next step is to reduce it to Cartesian coordinates, x, y and z and then the last step is to reduce it to Spherical coordinates, r, theta and phi. Q - What is the Indian Method ? A - The Indian method is to reduce the planet first to the Heliocentric Coordinate System, Manda Kriya, then reduce it to the Ecliptic Coordinate System, Parinathi Kriya and then reduce it to the Geocentric Coordinate System. Sheegra Kriya. Q - If both methods are different, why some say Indians plagiarised from the Greeks ? A - Such talk is all rot and nonsense. Q - What are the elements involved in the Western method ? A - In Western Astronomy, we have six orbital elements Mean Anomaly, m Argument of Perihelion, w Eccentricity, e Ascending Node, N Inclination, i, inclinent of orbit Semi Major ...
