极坐标方程积分区间的确定方法

Methods to Determining the Integral Interval of Polar Coordinate Equation

通过对本科院校理工类微积分教学现状分析,结合自己的教学经验,就计算极坐标方程r=f(θ)所围成的平面区域之面积时,从方程自身具有的一些特征,无需画出其图形,即可准确地给出其积分区间。

By analyzing the current situation of calculus teaching for science and engineering students in undergraduate shool, combining my own experience in teaching,this paper accurately provide the integral interval of planar regions of the area that the polar coordinate equation surrounds,and this result is not through drawing up the graphs,but come from the squation’s own characteristics.
