... b are rational then a(1 − 1/ 2) + b/ 2 is irrational and between a and b. Between any two irrational numbers there is a rational number because we can approximate any irrational number by a rational number from above or below. Theorem: All the rational numbers on the interval [0, 1] can be covered w ...

... • Apply modus ponens reasoning to generalized rules • Combines Universal-Elimination, and Modus Ponens – E.g, from P(c) and Q(c) and x (P(x) Q(x)) → R(x) derive R(c) • GMP requires substitutions for variable symbols – subst(θ, α) denotes the result of applying a set of substitutions defined by θ ...

Discrete Mathematics, Chapter 5: Induction and Recursion
... The basis step specifies an initial collection of elements. The recursive step gives the rules for forming new elements in the set from those already known to be in the set. Sometimes the recursive definition has an exclusion rule, which specifies that the set contains nothing other than those eleme ...
