2013-07-03 04:30:22 -0500 | asked a question | desolve_system problem with exp()/e^ Hi! I'm trying to solve ode system: x'=-2x+2y+e^t, y'=-2x+3y+3e^t This is what I tried in Sage:
But I always get this error:
If I remove the exp(t) it works fine, also if I replace the exp(t) with for example 2^t Sage gives me a solution. I already tried using e^t instead of exp(t) and tried some assumptions (assume(x >= 0), assume(t >= 0), etc.). Anyone got an idea what I'm doing wrong? Thanks in advance! |
