I hope someone can help me solving this:

Language: Python or Matlab.

Plot r₁(t) and r(t) in the same coordinate and over a period of one year. Try to separate the two curves.

r₁(t) =

Details:

r_e = 150 million km

T_e = 365 days

r_m = 0.384 million km

T_m = 27.3 days

t = 0

rj * cos(2nt/T;)) rj * sin(2nt/T;)) (r; cos(2mt/T;) + rm cos(2t/T) r; sin(2nt/T;) + I'm sin(2nt/Tm) rj * cos(2nt/T;)) rj * sin(2nt/T;)) (r; cos(2mt/T;) + rm cos(2t/T) r; sin(2nt/T;) + I'm sin(2nt/Tm)
