The coordinate space together with the coordinate axis is called the coordinate system. Any point that lies on the X-axis will have its coordinates in the form (x, 0, 0). The cartesian equation of the line is 3x + 1 = 6y … The coordinate space together with the coordinate axis is called the coordinate system. These three coordinate planes divide the space into eight parts known as octants. Let’s take another plane perpendicular to both the existing planes. The intersection of these two perpendicular planes is a straight line. In three-dimensional space, we identify a point with respect to the distances from the three reference planes. Introduction to Three-Dimensional Geometry Class 11 notes would provide you with an effective preparation for your examinations. The formulae list covers all formulae which provides the students a simple way to study of revise the chapter. Coordinate Axes In a 3d space, three parameters are required to find the exact location of a point.
