Abstract
On the basis of Coordinates vector computing formula in the Cartesian coordinate system,using linear transformation,we transform the questions in affine coordinate system into those in Cartesian coordinate system and give Vector coordinates computing formula in general affine coordinate system,which makes simpler the calculation of the length and angle problem and discussion of Parallel and vertical problems.
