Position vector in cylindrical coordinates.

In the polar coordinate system, the location of point P in a plane is given by two polar coordinates (Figure 2.20). The first polar coordinate is the radial coordinate r, which is the distance of point P from the origin. The second polar coordinate is an angle φ φ that the radial vector makes with some chosen direction, usually the positive x ...polar coordinates, and (r,f,z) for cylindrical polar coordinates. For instance, the point (0,1) in Cartesian coordinates would be labeled as (1, p/2) in polar coordinates; the Cartesian point (1,1) is equivalent to the polar coordinate position 2, p/4). It is a simple matter of trigonometry to show that we can transform x,yIn Cartesian coordinates, the unit vectors are constants. In spherical coordinates, the unit vectors depend on the position. Specifically, they are chosen to depend on the colatitude and azimuth angles. So, $\mathbf{r} = r \hat{\mathbf{e}}_r(\theta,\phi)$ where the unit vector $\hat{\mathbf{e}}_r$ is a function of …This tutorial will denote vector quantities with an arrow atop a letter, except unit vectors that define coordinate systems which will have a hat. 3-D Cartesian coordinates will be indicated by $ x, y, z $ and cylindrical coordinates with $ r,\theta,z $ .

Points with coordinates (ρ, π 3, φ) lie on the plane that forms angle θ = π 3 with the positive x -axis. Because ρ > 0, the surface described by equation θ = π 3 is the half-plane shown in Figure 5.7.13.

The "magnitude" of a vector, whether in spherical/ cartesian or cylindrical coordinates, is the same. Think of coordinates as different ways of expressing the position of the vector. For example, there are different languages in which the word "five" is said differently, but it is five regardless of whether it is said in English or Spanish, say.In spherical coordinates, we specify a point vector by giving the radial coordinate r, the distance from the origin to the point, the polar angle , the angle the radial vector makes with respect to the zaxis, and the ... a particle with position vector r, with Cartesian components (r x;r y;r z) .

The calculus of higher order tensors can also be cast in terms of these coordinates. The position vector of a particle has a magnitude equal to the radial distance, and a direction determined by er. Thus, ... Note that when using cylindrical coordinates, r is not the modulus of r. This is somewhat confusing, but it is consistent with the notation used by most books. Whenever we use cylindrical coordinates, we will write
