R is a collection of (statistical) data analysis tools.
Strictly speaking it cannot perform the functions you mention.
Yet I have been able to do most of the things you want using
tools contained in R and in R packages (you can load R packages
from the command line in R). And I HATE programming in any form!
But I would have to write a small manual for you :)
I only mentioned R because you can easily make excellent graphs with it.

As has already been mentioned you can use computer algebra 
symbolic computation packages like maxima. yacas and octave.

Maxima (in combination with for example the gui wxmaxima)
will do most of what you want and uses gnuplot.
(It is Lisp oriented).

Yacas is also good AND can be used in combination with R
and from within R if you load the R package 'Ryacas'.
Then you can also use the excellent R graphics facilities.
(see for example: http://cran-mirror.cs.uu.nl/ for Ryacas)

Maxima, octave and yacas have Fedora packages.

Also worth looking into are the combinations:
Euler+Yacas (Windows only)
