Transformation In Several Problems Of Applied

Abstract: In this paper, Orthogonal transformation、Affine transformation、Projective transformation. and the define of their especially examples and related property are mainly induced. Their application in Mathematics problems and in Life actual are discussed, making use of affine transformation may carry out Quadric curve converts mutually.

Key words: Orthogonal transformation；Affine transformation；Projective transformation.
