The Discussion of the Calculation About the Area of Curve Surface of Rotation
Abstract:The calculation about the area of curve surface of rotation is an im-
portant part of higher mathematics. Firstly,this paper discusses an formular which can be used to calculate the area of the curved surface of revolution generated from a circular motion of a line on a planar currilinear;secondly,this paper discusses an formular which can be used to calculate the area of the curved surface of revolution generated from a circular motion of line which get through axis polaris; lastly, using of the element method of the integral,we gave the general calculation formular of the area of the curve surface of rotation in arbitrary rotation angle with space curve.
Key words: The curved surface of revolution;Area;The method of calculation
