Usually denoted x, r, or s, it corresponds to the straight line segment from O to P .These axes allow us to name any location within the plane. In three dimensions, we define coordinate planes by the coordinate axes, just as in two dimensions. There are three axes now, so there are three intersecting pairs of axes. Each pair of axes forms a coordinate plane: the xy-plane, the xz-plane, and the yz-plane (Figure 2.26).Cylindrical coordinates are a generalization of two-dimensional polar coordinates to three dimensions by superposing a height (z) axis. Unfortunately, there are a number of different notations used for the other two coordinates. Either r or rho is used to refer to the radial coordinate and either phi or theta to the azimuthal coordinates.The TI-89 does this with position vectors, which are vectors that point from the origin to the coordinates of the point in space. On the TI-89, each position vector is represented by the coordinates of its endpoint—(x,y,z) in rectangular, (r,θ,z) in cylindrical, or (ρ,φ,θ) in spherical coordinates.1 Answer. Sorted by: 3.
