Hi,
I am expanding the Taylor series for an 8-dimensional exponential function
and Sage is taking too much time as the the number of terms are increased.
I am using Sage in notebook through VirtualBox. If I use Sage through
terminal on my own PC, will it faster its execution? Any other suggesti
Looks great, thanks for all the help!
I'll see about messing around with complex_plot a bit to support pure zero
plots, if it amounts to something I'll get back in touch...

Try this:
z,n = var('z,n')
@interact
def _(f = ((z+1)^n-abs(z^n+1)), n = (2..10), B=(2..10)):
f = f.subs(n=n)
show(f)
show(complex_plot(f, (-B,B), (-B,B)))

Okay, so the following works:
z = var('z')
n = 2
@interact
def _(f = ((z+1)^n-abs(z^n+1)), B=(2..10)):
show(complex_plot(f, (-B,B), (-B,B)))
But the following doesn't:
z = var('z')
@interact
def _(f = ((z+1)^n-abs(z^n+1)), n = (2..10), B=(2..10)):
show(complex_plot(f, (-B,B), (-B,B)))

Ah, that's unfortunate. Might be a fun summer project to try to implement,
if I knew where to start.
On another note: I really like the @interact annotation. I'm messing around
with it, because I would like to add another parameter to my plot - an
integer representing an index in a discrete fam

Thanks, this is exactly what I was looking for!
In fact, I had tried out complex_plot but I must have been using a
different color function or something, because the roots were much less
apparent to me. Not sure why I couldn't figure this out on my own...
I suppose I have two follow-up question
can replace z = a + bj and then solve the system of nonlinear equations Re {
z} = 0 and Im {z} = 0

You might find complex_plot useful. For

Sage. I ran ./sage -notebook , and created an admin account and a

The load() and attach()ed files should obviously be treated the same
(except for the reloading part), and offer a unified interface. Right now
that is IMHO a lot of spaghetti code that grew over the years. The fact

The plot contains more information than just the region of zeroes. Usually
the phase information is quite interesting. I don't think we have a
function to just give you the zeroes (which is numerically difficult)
