Description
The following should probably raise an error:
var('t') A = function('A',t) B = function('B',t) de1 = diff(A,t) == -k1*A+k2*B de2 = diff(B,t) == k1*A-k2*B sol = desolve_system([de1,de2],[A,B],ics=[500,0])
Or conceivably it should correspond to A(500)=0
and leaving B(500)
unevaluated, but in that case it should be checked whether that is really what happens, and well-documented.
