Python solve coupled ode
WebMy question is about how I can solve a coupled system of ODE's, and print out the variables in a plot. I am solving for an q value and an e value, seen in this set of coupled ODE's below: d q d t = 48 5 π M 2 ( 2 π M q) 11 / 3 e 1 + 73 24 e 2 + 37 96 e 4 ( 1 − e 2) 7 / 2, d e d t = − 304 15 M ( 2 π M q) 8 / 3 e 1 + 121 304 e 2 ( 1 − e 2) 5 / 2.
