You should always try the other options Sage offers:
sage: integral(cos(x)/(1+sin(x)), x, -pi/6, pi/6, algorithm='sympy')
log(3)

Hello sage-support team and thanks for this space. The problem I'm
having is the solution I get on sage when solving the following inequality
[(4*x+5)/(x^2)>=4/(x+5)]. It gives me the wrong answer ([x < -5], [x >=
-1]), the answer should be [x<-5],[-1<=x<0],[0http://www.wolframalpha.com/inpu
Hello sage-support team, im in the learning process of sage, so im working
on some basics problems, like solving inequalities. And when i try to solve
this problem (4*x + 5)/(x^2)>=4/(x+5) im getting this answer [[x < -5], [x
>= -1]], which is wrong.

Works well for me, with sage 6.9 on Ubuntu 14.04 64bits:
In[1]: plot(sin(x^2), (x,0,4), axes_labels=['$x$','$y$'])
in the Jupyter notebook results in a nice inline matplotlib graphic.

+1 for the weird behaviour of symbolic integration...I computed it quicky
without comp as integral -f'/f where f(x) = 1+sin x, whose solution seems
to be a log f function, and since f equals 0 only f for x = -pi/2 + 2k pi
(when sinx = -1), I don't know from which movie is "divergent" coming from
HG's last post translated (as accurate as I can :-)) ...
I I found the following hint : when that file is located in $HOME
directory, then mathjax can be launched.
It looks like the path to subdirectory is not well handledand i don't
know how to fix it.

J'ai remarqué que si le fichier est dans home alors il trouve bien mathjax,
donc c'est un problème de chemin vers un sous répertoire mais je ne sais
pas comment le régler.

I don't understand your call for numerical integration because I chose one
example at :
http://doc.sagemath.org/html/en/reference/calculus/sage/gsl/integration.html
and both twp examples work at sagemathcell
numerical_integral(cos(x)/(1+sin(x)), -pi/6, pi/6) # (1.0986122886681096,
1.21970465
I've tried to integrate cos(x)/(1+sin(x)) on [-pi/6 , pi/6] with the
"integral()" command in a Sage Worksheet in SageMathCloud and on
SageMathCell as well.
Each time I was told that the integral is divergent...
As far as I know, this function is continuous on this interval, and the
integral is e
