Yep, that did it. Comparing the path variables showed them to be quite
different. I've added the following to my init.sage:
os.environ["PATH"]+=":/usr/texbin:/usr/local/bin"
and everything runs happy. Just adding /usr/texbin didn't work because Sage
also needs to find 'convert' which I have
The paths are definitely different for terminal launched and app launched
Sage, and app launched Sage doesn't include /usr/texbin.
Sorry to sound so helpless, but what syntax would I use to add it to my
init.sage? I don't currently have one, and I've come up blank searching for
it in the docum
I'm noticing that the problem only happens when launching Sage.app. If I
install the command line version, it detects Latex just fine. Also, if I
launch the sage binary from within the Sage.app package (the one in
Contents/Resources/sage, not the one closer to the app root), it also seems
to
I've installed MacTex and I'm still having the same problem. You won't see
this problem for most typeset results because Sage attempts to use jsMath,
but it turns up when typesetting a result that jsMath can't handle (or if
you force it to use go straight to latex by using the jsmath_avoid_list
like g(x)=sin(x) + `f(x)`
Am I making sense, or just digging my credibility hole deeper? In my
defense, I've only had a couple days of playtime with the system so far...

gain confidence, lose track of
these various function types, and not realize that the results I'm
getting are incorrect.

Should mention this is 4.3.3, 64 bit OS X 10.6.2

and
var('x')
T=RealDistribution('gaussian',1)
f=lambda x: sin(x)+ T.get_random_element()
plot(f(x),(x,0,2*pi))
-
all give me a clean sine with a random offset, rather than sine
+noise...

Hi--
I'm trying to figure out how to use RealDistributions to model noise.
For example, I would like to model a signal+noise and tried using this
construct:
T=RealDistribution('gaussian',1)
f(x)=sin(x)+T.get_random_element()
plot(f(x),(x,0,2*pi))
Unfortunately, that only calls get_random_element
For anyone interested, it looks as though the GiNaC project has
released a fix:

I've posted this to the dev list as well.

The code with the .substitute line seems to work for (t%30 <> 0) so I
think I've formatted my equations properly.
Apologies if I'm doing something horribly hackish-- I'm new to Sage.
Any other ideas?

Try
plot(f(t), ymax=17, ymin=-12)

While waiting to be approved, I think I narrowed this down to a very
simple test case.
atan2(3,0) --> 1/2*pi
atan2(-3,0) --> -1/2*pi
atan2(pi,0) --> 1/2*pi
atan2(-pi,0) --> RuntimeError: power::eval(): division by zero
Any ideas how to get around this?
Thanks--
