Review integration by parts

step inference rule input feed output step validity (as per SymPy)
1
  • 0000111299: declare identity
  • number of inputs: 0; feeds: 0; outputs: 1
  • Eq.~\ref{eq:#1} is an identity.
  1. 8489593958
    \(d(u v) = u dv + v du\)
no validation is available for declarations
2
  • 0000111282: subtract X from both sides
  • number of inputs: 1; feeds: 1; outputs: 1
  • Subtract $#1$ from both sides of Eq.~\ref{eq:#2}; yields Eq.~\ref{eq:#3}.
  1. 8489593958
    \(d(u v) = u dv + v du\)
  1. 0009492929
    \(v du\)
  1. 8489593960
    \(d(u v) - v du = u dv\)
Not evaluated due to missing term in SymPy
3
  • 0000111268: swap LHS with RHS
  • number of inputs: 1; feeds: 0; outputs: 1
  • Swap LHS of Eq.~\ref{eq:#1} with RHS; yields Eq.~\ref{eq:#2}.
  1. 8489593960
    \(d(u v) - v du = u dv\)
  1. 8489593962
    \(u dv = d(u v) - v du\)
Not evaluated due to missing term in SymPy
4
  • 0000111608: indefinite integration
  • number of inputs: 1; feeds: 0; outputs: 1
  • Indefinite integral of both sides of Eq.~\ref{eq:#1}; yields Eq.~\ref{eq:#2}.
  1. 8489593962
    \(u dv = d(u v) - v du\)
  1. 8489593964
    \(\int u dv = u v - \int v du\)
recognized infrule but not yet supported
5
  • 0000111341: declare final expression
  • number of inputs: 1; feeds: 0; outputs: 0
  • Eq.~\ref{eq:#1} is one of the final equations.
  1. 8489593964
    \(\int u dv = u v - \int v du\)
no validation is available for declarations
