RE: Help !! plot roots of an expression
It would help if you posted an evaluable example to the group. How could one possibly find roots for the example that you give? David Park djmp at earthlink.net http://home.earthlink.net/~djmp/ From: mintoo [mailto:varun.tangri at gmail.com] I have a polynomial. A simple example is like this (w-w1) (w + 2 q +en^2 + s w^3) + r The actual example is more complicated. It is a function of several variables e.g. q, en, s, r etc.. I also need to Collect & FullSimplify this expression. Finally, from that result, I want to plot the roots of this polynomial (imaginary & real part) vs. q (say) or vs en etc.. other variables can be given fixed values. I'll the thankful if you give me hints how to do this!!
