Does any one know how to graph polynomial on either octave or maxima.
There is instruction on graphing trig function but not polynomials
octave:7> x=-2:.1:2;
octave:8> plot(x,x.^2)

remember to use operators like .^, .+, .* where you're working with the x matrix, because those do cell-by-cell operations, whereas ^ + and * do matrix operations. (Although it's perfectly OK to write a polynomial as 3*x.^2+3*x+x because + and .+ will be the same, and * is the same as .* when you're multiplying a scalar)

I usually have a GPG digital signature included as an attachment.
See http://www.gnupg.org/ for info about these digital signatures.
My key was last signed 10/14/2003. If you use GPG *please* see me about
signing the key. ***** My computer can't give you viruses by email. ***
