考研数学中旋转体的体积计算

Mathematics in the Rotating Object Volume Calculation

旋转体的体积计算是考研数学中的一个重要知识点,但一般的教材或考研资料中只给出了计算旋转体体积计算的基本公式,而学生又不能理解这些公式并对其进行拓广,为此。

The calculation of rotating object volume in mathematics is an important knowledge point in post graduate entrance examination,but in general textbooks or graduate-study exam data it is only given to the rotation formulae of calculating the volume body,and students can ＇t understand the formula and extend it,therefore,it is necessary to discuss the method of calculating the volume of rotating body.
