Hello,

I would not rely on numerical methods to get 'all' results. Using calculus is probably a better idea.

Thanks Roger. Your explanation is clear. But don't know how to convert this idea to a plot...

look up the help on 'plot'. the most simple way to plot is just: plot(x,y) (where the vectors x & y have to be of same length)

yes you can. you would have to redo all the alggebra substituting C instead of 0.25.

first about the error: if you have a dimension mismatch you should give the commands:
