WebThis process, called mathematical induction, is one of the most important proof techniques and boils down a proof to showing that if a statement is true for k, then it is also true for k + 1. We devote this chapter to the study of mathematical induction. 6.1.2 Formalizing Mathematical Induction WebFinally, to prove that factorial x > 0, the solver figures out that factorial x = x * factorial (x - 1). From the recursive lemma invocation, we know that factorial (x - 1) > 0, and since we’re in the case where x > 0, the solver can prove that the product of two positive numbers must be positive.
