英语词汇“proof by induction”的翻译、意思、用法、释义-英汉经管词典

单词	proof by induction
释义	proof by induction The method of proving a sequence of statements by showing that if one particular case is true, the next must also be true; but it is true for the first, so it must be true for the rest. Consider for example the statement that the sum of the first N terms of a geometric progression a, ar, ar², etc. is given by S_N = a(r^N - 1)/(r - 1). This is clearly true for N = 1. Suppose it is true for N. The N + 1th term is ar^N. But 0198607679.proof-by-induction.1.jpg This is S_N with N + 1 substituted for N, so if the formula for S_N is correct for N it is correct for N + 1. But we know it is true for N = 1, so it must be true for all N ≥ 1.
