1、universal space rectangular coordinate system

2、A Method of 3D rectangular coordinate transformation adapted to any rotation angle

3、The CORDIC algorithm is adapted to convert the polar coordinate image to the rectangular coordinate image, while cubic spline interpolation is used to interpolate the vacant pixels.

4、New coordinate systems are not rectangular coordinates system and new connections and regularities of nuclear system distribution are found.

5、Objective:To establish three-dimension (3D) rectangular coordinate and to obtain relevant parameters of artificial tooth morphology for full denture.

6、In Fig. 6-1(c), the motion of a particle is referred to by a rectangular coordinate system.

7、The equations are written in rectangular coordinates .

8、We have rectangular coordinates, we have cylindrical coordinates and we have spherical coordinates.
