A Surface and character in N-D Eucilidean spaces
ABSTRACT
By the research of the definition ,equation form ,tangent plane and the definition and equation of the normal of the surface in 3-D Eucilidean,that of the surface in N-D Eucilidean is r much work ,the basis solutions of that of the surface in N-D Eucilidean are while some deduced results in this paper are proved,the characters and properties of the surface in N-D Eucilidean are studied initially.
Keywords: N-D Eucilidean spaces surface tangent plane normal.
