I have the following piece of code
f(x) = 2*unit_step(x)
u = function('u')(x)
eqn = diff(u,x) + u == f(x)
v = desolve(eqn, u,ics=[0,0])
solve(v,x)
which gives me `[x == 0, sgn(x) == -1]` as solutions to the last equation. Could you help me find a way for Sage not to stop at `sgn(x) == -1`?
ThanksThu, 15 Jun 2017 02:20:44 -0500http://ask.sagemath.org/question/37948/equation-with-sign-function/
