摘要
本文将在有限区间的积分即图形相乘,经证明可扩展在无限小区间上应用,其结论也是正确的。
In this paper, the auther attemptsto prove that the result of the integral formulaf of limited interval' dx' i.e.graph-multiplication, may have ingenious applica-tion after verification with derivation it has been proved that the application of this integral formula may be extended to infinitcsmal interval.
