当一个问题会出现相当多乃至无穷多的情形时,可以从简单情形或特殊情形入手,通过对简单情形或特殊情形的试验,发现一般规律或作出某种猜想,从而找到解决问题的途径或方法,这种研究问题的方法就是归纳猜想法。猜想是根据某些已知事物和知识对未知事物及其规律性的似真推断。数学猜想是根据已知数学条件和数学原理对未知的量 When a problem will appear quite a lot or even a lot of situations, you can start with the simple situation or special circumstances, through the simple case or special circumstances of the trial, find the general law or make some guess, to find ways or means to solve the problem , This method of studying the problem is to conclude the conjecture. Conjecture is based on some known things and knowledge of unknown things and its regular speculation. Mathematical conjecture is based on known mathematical conditions and mathematical principles of unknown quantities
