Tata! You clearly know *something* about it, or you wouldn't have done as
well as you have finding stuff
Sometimes a workaround is possible:
sage: x = var('x')
sage: y = function('y', x)
sage: C = var('C')
sage: f = desolve(diff(y,x) + y, y, ics=[0,C]); f
C*e^(-x)
sage: c = var('c')
sage: f = desolve(diff(y,x) +c*y, y,ivar=x, ics=[0,C]); f
C*e^(-c*x)
