The function call FactorDerivative(v,R) returns a sequence ,  such that  is the derivation operator, and, u is the dependent variable, associated to  (see DifferentialAlgebra). The argument v must be a derivative of R, or of its embedding ring if R is an ideal.

This command is part of the DifferentialAlgebra:-Tools package. It can be called using the form FactorDerivative(...) after executing the command with(DifferentialAlgebra:-Tools). It can also be directly called using the form DifferentialAlgebra[Tools][FactorDerivative](...).

The opts arguments may contain one or more of the options below.

notation = jet, tjet, diff or Diff. Specifies the notation used for the result of the function call. If not specified, the notation of v is used.

memout = nonnegative. Specifies a memory limit, in MB, for the computation. Default is zero (no memory out).
