MULTIPLE PROOFS

摘要

In mathematics as a science proofs play an irreplaceable role - they serve for verification of our propositions. In school mathematics proofs fulfil several other functions -deeper explanation of theorems, deduction of formulas, development of thinking and problem-solving strategies, etc. We believe that it is not right to lessen the amount of proofs in school mathematics. Quite the contrary, learners should be exposed to multiple proofs of single propositions so that they can choose the most comprehensible one for them. In this paper we demonstrate the idea through computation of the limit of sequence lim {formula}.
