About This Video:
An octant is one of the eight divisions of a Euclidean three-dimensional coordinate system.
There is one to one correspondence between the points in space and ordered triplet (x,y,z) of real numbers.
The coordinates of points on the x axis are of the type (x,0,0), on the y axis are (0,y,0) and on the z axis are (0,0,z)
The x coordinate of the point in the YZ plane is zero, Z-coordinate of a point in the XY plane is zero and y-coordinate in the XZ plane is also zero.
