[sage-devel] Test the "binomial" function in an expression

Hello, I play with expressions, and transform sin(x) to (exp(i*x)-exp(-i*x))/2. So I use a lot of test as var ('x') y = cos(x) # or any other expression" op = y.operator # so op == cos if op == cos : ... # this test is fine, not the next one else : ... Now I want to test an expression

Hi Burcin and Karl-Dieter, // 1 // And what do you think about log ? Look at these test : exp(x).operator() == exp # is True, and all(?) trigonometric functions are fine log(x).operator() == ln # is True, yes the alias ln is better than the log name log(x).operator() == log # is False (this

there are no name about usual functions (sin, cos, log, exp) in this file So I don't understand how this filter (from int(0) to integer(0)) can be done. Are they just call just arround Pynac. But I feel it's ...local/lib/python2.6/site-packages/sage/functions/log.py Francois M. -

Dear all, Students discover Sage for mathematical computations, and the functions are the most usual way to write mathematics. So I prefer a light interface with the matrix function "trace(...)". The determinant is a function and a method... but trace is only a method. And .methods() aren't ful

I have pushed and chased all of the changes necessary for having sage building with python-2.7 out of the box in the last few months for example. Getting sage itself to move to python-2.7 is a little further away but Gentoo and Mandriva have already moved on. Recently Paulo chased an issue he had with
