My professor asked this question to the class. How much should the line of nodes have rotated for a true sun-synchronous orbit? What makes an orbit a true sun-synchronous orbit? Also, I calculated the estimated orbit in MATLAB. But, it was different than the true orbit. What causes the discrepancy between an estimated orbit data vs the actual orbit data? Is it just the numerical error or could it be things like the Sun and Moon or Atmospheric drag?

When faced with the challenge of searching a text string for any one of a specified set of k patterns, how would you modify the Rabin-Karp method? Beginning with the assumption that all k patterns have the same length, we may proceed. Then how about making your approach more broad so that varying lengths of patterns may be accommodated?
