The same position vector "'x "'represented in two 3d rectangular coordinate systems each with an orthonormal basis, the cuboids illustrate the parallelogram law for adding vector components.
23.
Rectangular coordinates in the plane can be used intuitively with respect to one's current location, in which case the " x "-axis will point to the local north.
24.
In a 2-D rectangular coordinate system : There is a circle of radius R at the location ( x, y ) = ( 0, h )-on the y-axis.
25.
Given the above information, and only the above information, it is desired to construct the actual 3D locations of the speakers and the measuring points in space, ideally in a rectangular coordinate system.
26.
The locations of points in three-dimensional space are most conveniently described by three cartesian or rectangular coordinates, " X ", " Y " and " Z ".
27.
For example, the velocity of a particle is invariant when switching from rectangular coordinates to curvilinear coordinates, but is not invariant when transforming between frames of reference that are moving with respect to each other.
28.
This geometrically has the interpretation that a rectangular coordinate system is mapped to another rectangular coordinate system, in which the norm of the vector "'x "'is preserved ( and distances are preserved ).

It is easy enough to " translate " between polar and rectangular coordinates in the plane : let, as above, direction and distance be " ? " and " s " respectively, then we have
