[積分] 習題
這是Stewart的《Calculus》5E上的習題。
Section 6.2 Volumes:
67.A hole of radius r is bored through a cylinder of radius R > r
at right angles to the axis of the cylinder. Set up,but do not
evaluate,an integral for the volume cut out.
r
Ans: 8∫ √(R^2 - y^2)√(r^2 - y^2) dy
0
我搞不太懂這題上所說的圖形是什麼樣子,所以導不出積分的形式,
想請問題目說得是什麼圖形?
