2017-07-16 02:42:07 +0200 | asked a question | Solving system of ODE gets "ValueError" I'm trying to solve a system of ODE using desolve_system but get "ValueError": gets: the problem seems to be sin(t) factor, without it the system solves with no problem. Also desolve(de1, f) has no problem. What is going on here? Thanks in advance! |
