{{{
sage: y(x) = function('y',x)
sage: desolve( y(x).diff(x,2) == 0, y(x))
k2*x + k1
sage: desolve( y(x).diff(x,2) == 0, y(x), [0,0,1])
x + y(0)
sage: desolve( y(x).diff(x,2) == 0, y(x), [0,1,1])
x + y(0)
}}}
It seems desolve instead of using the given initial
value of y at x=0, it literally passes "y(0)" to maxima.
