WebIn backward reasoning, the proof begins with the theorem statement as the goal, which is then gradually transformed until every subgoal generated along the way has been proven. In this case, the proof of A /\ B begins with that formula as the goal. WebJan 25, 2024 · The ProofObject, however, will have the same form, using the general syntax ProofObject [logic, theorem, axioms, proofinfo]. The theorem and axioms must be expressed in the given logic, and the proofinfo will strongly depend on that logic.
