Dear Group:  I think some of the errors may be due to copying from a
Mathematica notebook directly to the email.  Some of the cells are in
Input form and don't translate to the email as they appear in the
notebook.  In a separate email, David suggested converting Input cells
to Inputform as a precaution when sending code to the group.  I will try
to remember that in the future.  Thanks,  Darrell Bosch

[Some of the errors mentioned come from problems with how email
 is transmitted.  If posts are not pure ascii they can sometimes
 contain extra spaces or = signs.  I try to detect these but it
 it not always possible - moderator]

Your code is full of errors. Many symbols are undefined so there is no
one could calculate a value or make a plot.  What is something like
supposed to mean? What is Lo=g[size] supposed to mean? In one place you
'siz e' with an extra space. No piece of what you have posted makes any
sense or will evaluate, including the very first statement.

If you cleaned up your typing and provided definitions for all the
you might actually find that it worked, or at least be in a position to
some useful help.

Dear Group,  Thanks to several of you for providing good suggestions to
my previous inquiry.  In the program below I am trying to solve an
equation for v, derive the solution with respect to size, and plot the
resulting solution.  The problem I have is in running the plot command.
I am trying to set numerical values for variables in the derivative
(other than size) and plot the derivative for size, but Mathematica
won't recognize the settings for the other values. Would appreciate any
suggestions.  Darrell



 sol3=D[v /.  sol2[[1]],size]
