I requested the creation of this article. I imagined that it would be a discussion of writing equations using the symbols of vectors such as gradients, curls, dot products, etc.. Also, I would like a discussion of how this was developed to be able to express physics/engineering equations independently of the coordinate system. A good example are the Navier Stokes equations article which expresses these equations in vector notation, indicial notation as well as Cartesian Coordinates (but not in spherical, polar, cylindrical). I planned on one day doing this myself, but I suspect it will be a while before I get to it. But I think it is a useful topic, especially since indicial notation has its own page.

Work in progress
Still working on this! Hit the wrong button.—Kbolino 13:59, 31 October 2007 (UTC)
I have updated this page to reflect my knowledge of the different notations as best I can and improve the organization. Some of it is solid (rectangular vectors), some of it is nearly invented (polar, cylindrical, spherical), and the rest somewhere in between. There is some information missing, such as how to write vectors in other spaces (complex space, continuous function space, polynomial space, etc.) Of course, none of it is cited--which is probably more important than the content itself. Hopefully this will provide a good starting point, from which the useful information can be referenced and improved, and the less useful (and accurate) information can be pruned.—Kbolino 08:14, 5 November 2007 (UTC)
126.96.36.199 changed the first sentence as follows (diff: )
The cross product of two vectors (in or )...
The cross product of two vectors (in or or whatever Field)...
with the edit comment: fixed inaccurate statement in cross product - it can be from any field whatsoever.
To facilitate understanding of vectors for the more visual among us, could someone create some images illustrating like the difference between a scalar, 3d vectors, and the like? (I would except I'm not too clear myself).
Add example notation to "shorthand notation" (second paragraph)
I was frustrated searching for where does the notation "r with a tilde below it" come from until I noticed the line in the second paragraph that says it's shorthand notation. I think we should include an example or two. 1Minow (talk) 14:23, 22 March 2014 (UTC)
ISO 80000-2:2009 recommends italic bold serif for vector variables, but an example can't be given due to limitations in Wikipedia's LaTeX implementation and my own knowledge of Wikipedia markup. So I gave the example in CSS format instead with
<span style="font-family: serif; font-size: large; font-weight: bold; font-style: italic">v</span>. If anyone knows how to bold, italicize, and serif a single letter using Wikipedia's implementation of LaTeX, please revise. Adelphious (talk) 00:29, 4 April 2016 (UTC)
