numerical methods with programming 3. The time equation for elliptic orbits has the form M -Esino where: M is known as the mean anomaly, ø(in radians) is known as the eccentric anomaly and E (between 0 and 1) is the eccentricity of the elliptic orbit. For a given value of E and for a given value of M in the range n M(n1) the solution for behaves as follows: M when is an even integer; M when n is an...
