[LON-CAPA-users] Implicit Answer Response

If I wanted students to enter in an answer along the lines of:

-4cos 500t A

Where A is unit Amps

What would be the best way to go about this?
I was thinking just having students enter in a string, but that won't
work even if they do all put the answer in Amps instead of mA or
whatever.  There would be too many variations.. like "-4*cos 500t A" or

What do you suggest?

Hi Roderigo,

I have recently upgraded my server OS to FC4.

My experience is that the "Partitioning your Drive" section on this Web 
page you have been referred to is outdated, specifically:

    "You may want to use the automatic partitioning feature of the
    installer, however you should review the results and be prepared to
    modify them. LON-CAPA resource files are stored in the /home
    directory, so the majority of the disk space should be allocated
    here. If you have 20 GB of space for FC4, /home should receive at
    least 10 to 12 gigs. Since MySQL uses the /var filesystem to store
    its databases you should have at least 4 gigs of space available on
    /var. Be sure to include adequate swap space. A minimum is 512 Megs,
    but you should typically have 1 or 2x as much swap space as you do
    physical RAM."

My understanding is that /var is not used.  Typically, lon-capa is 
divided into the following directories:


How much memory is allocated to each of these directories depends, of
course, on your particular machine parameters, which ideally are
from the number of users you intend to serve.  (Although, cost or
availability are generally the driving factors.)
