Query: On Expansion of a Solution of General Non-autonomous Polynomial
  Differential Equation   We give a recursive formula for an expansion of a solution of a general
non-autonomous polynomial differential equation. The formula is given on the
algebraic level with a use of shuffle product. This approach minimizes the
number of integrations on each order of expansion. Using combinatorics of trees
we estimate the radius of convergence of the expansion.
