To make some use of the summer, I am in the process of updating some problems to using MathObjects as well as writing some new problems. Is there a single place where one can find the methods for the the various mathObjects?

Go to http://webwork.maa.org then click on "Authors" and then on "MathObjects" to see what information has been posted so far:

The wiki can be edited by anyone so feel free to add clarifying information for those passages which are not clear.

The document http://webwork.maa.org/wiki/Introduction_to_MathObjects

has a list of the most common methods for MathObjects -- and should be enough for most purposes. It is somewhat difficult to compile a complete list of methods for an object since the methods available can be augmented at any level of the object hierarchy.

Particularly useful for trying out MathObjects constructs is the first of the PGLabs listed at http://webwork.maa.org/wiki/PGLabs

Thanks. I thought that I had looked through most of these places. Maybe I should ask a more direct question. Is there a method that returns the magnitude of vector?

Context("Vector"); $v = Compute("<3,5,6>"); $norm = norm($v); TEXT($norm); Result: 8.3666 You can try it out at http://hosted2.webwork.rochester.edu/webwork2/cervone_course/setAIM-Talk/82/the following works as well:

Context("Vector"); $v = Compute("<3,5,6>"); $norm = $v->norm; TEXT($norm);

Thanks. This is what I was looking for.

I've transfered some of that information to the wiki pages at

http://webwork.maa.org/wiki/MathObjects_reference_table

You're right that

there was no list of additional operations for vector on the wiki.

When starting out using MathObjects it's worth flipping through Davide's two presentations for ideas.
