The Kepler equation is: M = E - e Sin(E); where M is the mean anomaly and E the eccentric anomaly and e is the eccentricity.
we get it from integrating dr/r' and changing variables to E, how did Kepler get it without calculus and using only his laws.
Another thing how did he see his second law (areal velocity) without differentiation.
