| Abstract: | Based on the nature of function f (x)which is symmetrical to straight line x=m,the paper deduces the volume formula of the rotating object which is formed by rotating the planar graphs that is enclosed by the curves of these kinds of functions f 1 (x)?f 2 (x)and straight lines x=m-a?x=m+a one circuit around axisy. |
