본문통과인입선구형、선선형화면원주체등미분개념,급출료대정적분원소분석법경본질、경통속적리해,돌파료“정적분재궤하학상적응용”저일교학난점。
In this paper, we offer a more natural and popular way to comprehend the element analysis method of definite integral by defi-ning some differential concepts, such as linear rectangle, linear sector, plane cylinder and so on, so that we make a breakthrough on teaching difficulty about the application of definite integral to geometry.
