The Ingenious Application of Affine Transformation Through Turning"Ellipse"into"Circle"
Some important properties of affine transformations are commonly employed for solving issues in Euclidean geometry.Taking the real questions of recent college entrance examination as examples,this paper discusses the application of affine transformations in solving a series of problems related to finding area,slope of straight lines,extremum and constant values in ellipses.It ingeniously solves problems related to conic sections by transforming"ellipses"into"circles"and provides specific methods for flexible use of affine transformations in different types of problems.
