结论若a-b=n,则1/2a-1/2b=1/2(a-b)-1/2n.简称一半的差等于差的一半.以上结论虽然内容形式简单易懂,但它在几何解题中的应用非常广泛.现举几例,加以浅析,以供参考.
If ab=n, then 1/2a-1/2b=1/2(ab)-1/2n. The difference of the abbreviation is equal to half the difference. The above conclusion Although the content form is simple and easy to understand, it solves the problem in geometry. The application is very extensive. Now give a few examples, to analyze, for reference.
