Web3 / 7 Directionality in Induction In the inductive step of a proof, you need to prove this statement: If P(k) is true, then P(k+1) is true. Typically, in an inductive proof, you'd start off by assuming that P(k) was true, then would proceed to show that P(k+1) must also be true. In practice, it can be easy to inadvertently get this backwards. WebIncludes Address(2) Phone(3) Email(2) See Results. Statistics for all 1 John Ritzenthaler results: 77 yrs.
