You cannot have a vector V with spherical polar components defined relative to another vector.In a standard spherical polar coordinate system, the coordinates of a point P are given by (r,theta,phi) where theta is the polar angle, phi azimuthal angle, and r the Euclidean distance from the origin. Physics - Advanced E&M: Ch 1 Math Concepts (25 of 55) Cylindrical Coordinates:Point and Unit Vectors Michel van Biezen ... (29 of 55) Divergence of a Cylindrical Vector Field 1/2 - …

Given a unit vector A = x1,y1,z1 in cartesian, to transform into cylindrical just use the transform A. ρ ρ A. ϕ ϕ Z (cartesian)=Z (cylindrical) my question is, since x. ρ ρ = cos ϕ ϕ, is the ϕ ϕ that I am supposed to use the tan^-1 (y1/X1)? A: That’s right! 8/23/2005 The Position Vector.doc 3/7 Jim Stiles The Univ. Spherical Coordinates: We generally want to switch from rectangular to spherical coordinates when we are dealing with spheres or spherical surfaces. We will not go over the details here. 3-D Cartesian coordinates will be indicated by $ x, y, z $ and cylindrical coordinates with $ r,\theta,z $.. The magnitude of a directed distance vector is Cylindrical and spherical coordinates give us the flexibility to select a coordinate system appropriate to the problem at hand. Finally, unit vectors change according to the Jacobian matrix e.g. of Kansas Dept. of EECS The magnitude of r Note the magnitude of any and all position vectors is: rrr xyzr=⋅= ++=222 The magnitude of the position vector is equal to the coordinate value r of the point the position vector is pointing to! Specifically, they are chosen to depend on the colatitude and azimuth angles.

Preliminaries.

A scalar is just a fancy word for a real number. In Cartesian coordinates, the unit vectors are constants. In spherical coordinates, the unit vectors depend on the position. Find the Divergence of a Vector Field Step 1: Identify the coordinate system. So, $\mathbf{r} = r \hat{\mathbf{e}}_r(\theta,\phi)$ where the unit vector … A vector A in cylindrical coordinates can be written as (2.3) (A p, A^,, Az) or A a (2.4) where ap> a^, and az are unit vectors in the p-, <£-, and ^-directions as illustrated in Figure 2.1. ... Find the unit vector that has the same direction as vector that begins at and ends at . In general integrals in spherical coordinates will have limits that depend on the 1 or 2 of the variables.

In these cases the order of integration does matter. To find the unit vector u of the vector you divide that vector by its magnitude as follows: Note that this formula uses scalar multiplication, because the numerator is a vector and the denominator is a scalar. One way to identify the coordinate system is to look at the unit vectors.

Summary. Note that a^ is not in degrees; it assumes the unit vector of A. How to find {eq}\phi {/eq} spherical coordinates?

To convert an integral from Cartesian coordinates to cylindrical or spherical coordinates: (1) Express the limits in the appropriate form ... Find the cylindrical coordinates of the point. This tutorial will make use of several vector derivative identities.In particular, these: This tutorial will denote vector quantities with an arrow atop a letter, except unit vectors that define coordinate systems which will have a hat.

I feel that this is simply not possible given the information you have to hand.
