Abstract:We all know that analytical methods in polar coordinate are widely applied in resolving geometry problems. In this paper, the methods on how to analysis the property of geometry curve when we need not draw the graph were discussed in polar coordinate, for this, the examples of calcu- lating the area in polar coordinate were quoted.
Keywords:polar coordinate  area  distributed scope  symmetry  close
