I tested your function up to 100,000 with all the variations of f, and
they all worked after applying the patch for #847.

Thanks (I really like that!) but... While this approach worked well
with the numbers given, it generated the same error on larger values
of n.

Hi William et al,
I am running sage-2.8.13-i686-Linux-Ubuntu.tar.gz, reading

Hi,
Thank you; that solution fits the matter perfectly.
In Maple one typically write f:=x->x if one means a function instead
of an expression. Doing something similar in SAGE makes a *lot* of
sense, so I don't object inherently to the lambda notation, although
the default Python syntax ("lambda"
Hello,
This is an instance of http://trac.sagemath.org/sage_trac/ticket/847 .
I / we haven't had time to fix that one, but hopefully we can get to
it tomorrow. For now, you should make sure that f is an actual Python
function.
sage: f = lambda x: x
sage: Midpoint_Riemann_Sums(0, 5, f, 1000)

Our posts crossed paths. The download was ok, GUI tools were bad, bash
is good.
I will try building from source soon, but right now I'm eager to try
out SAGE and Python!
Thanks, Max

I've installed the latest SAGE and encountered a similar-but-different
error,
this time when attempting to import module
"sage.rings.number_field.number_field_base".

Again, I don't understand the bug but piecewise seems to work better using
lambda functions.
sage: f = lambda x: x
sage: fp = Piecewise([[(10,20),f]])
sage: fp.riemann_sum_integral_approximation(993)
148900/993
Next semester, when I have more time, I plan to revise piecewise.
Maybe I can look in
Thank you! The following code produces the same error.
f = x
fp = Piecewise([[(10,20),f]])
fp.riemann_sum_integral_approximation(993)
The student is doing this as an assignment for a class on how to write
programs to solve problems in mathematics. (Newton's Method, Riemann
sums, Fibonacci number
I'm not sure what the cause of the error is but, FYI, some Riemann sum stuff is
already implemented in piecewise.py.

Hi,
One of my students was writing a procedure to implement a Midpoint
Riemann Sum in SAGE. The procedure that she devised is given below,
and it looks reasonable enough to me. Unfortunately it generates a
SAGE exception (AttributeError, line 2051 of calculus.py) under
certain bizarre circumstanc

I downloaded the modified tarball. It untar'd without complaint.
However on running notebook() for the first time it bombed out, unable
to find /usr/local/lib/libintl.3.dylib.
