InnerDifferentiate

 Method with 2 overloads

• InnerDifferentiate​(AngouriMath.​Entity.​Variable,​System.​Int32)

  Summary

  power raw passes, with nothing simplified in between.
  Derivativef's simplification needs exactly this and not the public
  overload: it asks for the derivative and keeps the node when what comes back is
  still a Derivativef, so a simplification anywhere inside would ask
  that same node to simplify, which asks for the derivative again, without end.
  

• InnerDifferentiate​(AngouriMath.​Entity.​Variable)

  Summary

  This node's own rule of differentiation. Parts are differentiated by
  DerivativeOver(AngouriMath.Entity.Variable), which answers zero for a constant before a rule
  is asked.
  

  Parameter "variable"

  To derive over

  Returns

  The differentiated expression, or the Derivative node -- and zero for a node with no
  rule of its own that does not mention the variable: it is a constant in it, and the
  derivative of a constant is not an open question. A set is not a constant, whatever
  it mentions: { 1, 2 } + sin(x) is the set { 1 + sin(x), 2 + sin(x) }, and
  its derivative is { cos(x) }, which the derivative node reaches elementwise and
  a zero would flatten to the number cos(x).
