Earth's elliptic orbit : assume(ε>0,ε<1)...

Erratum : https://en.wikipedia.org/wiki/Kepler_problem instead of https://en.wikipedia.org/wiki/Kepler's_equation in my #21 post . In...

https://en.wikipedia.org/wiki/Kepler's_equation just gives at the end the Kepler's 1st law of my #17 post in general (...

In : var('θ,ε,t') assume(0<ε<1) assume(-π<θ<π) from sage.symbolic.integration.integral import indefinite_integral...

I can't edit my previous post ... There're (cos(θ)+1) as denominators , so we must precise : -π<θ<π

I'm back , sorry for long time . In short : ##L=r^2ω=constant## ( Kepler's 2nd law ) ##r=\frac{L^2}{GM(1+εcos(θ))}## ( Kepler's 1st...
