    Discrete Math Proof n^2 > n +1

    Homework Statement For any given n, where n is an element of the natural number set, prove n^2 > n +1, for all n > 1. Homework Equations This week in lecture we defined the greater than relationship as: Let S = Natural numbers Let R = {(a,b): \exists c: a = b+c} then aRb The...
