4.7.1.1 How to generate a mesh with quadrilateral elements?

http://mathematica.stackexchange.com/questions/137479/how-to-generate-a-mesh-with-quadrilateral-elements

 
I have the following code that generates a finite element mesh: 
 
Needs["NDSolve`FEM`"] 
order = 2; 
mesh = ToElementMesh[ 
DiscretizeGraphics[ 
GraphicsComplex[{{0, 4}, {5, 4}, {5, 0}, {8, 0}, {8,  ...

4.7.1.2 Why can't I plot Log[Gamma[x]] for x > 170?

http://mathematica.stackexchange.com/questions/137666/why-cant-i-plot-loggammax-for-x-170

 
Bug introduced in 11.0 
 
 
 
For some reason I can't plot Log[Gamma[x]] for values of x larger than approximately 170: 
 
Plot[Log[Gamma[x]], {x, 130, 200}, PlotRange -> All] 
 
 
 
 
It works perfectly well  ...

http://mathematica.stackexchange.com/questions/137692/finding-the-number-of-odd-quintinomial-coefficients

 
I am searching for the number of odd coefficients of 
 
$\qquad (x^4 + x^3 + x^2 + x + 1)^n$ 
 
for arbitrary $n$. 
 
It took some hours to compute the result for $n=12207$. There are $16333$ odd  ...

4.7.1.6 How to superimpose plots and graphics in the same coordinate system?

http://mathematica.stackexchange.com/questions/137408/how-to-superimpose-plots-and-graphics-in-the-same-coordinate-system

 
NB: I am aware that "plots" are graphics too, so the title would be more precisely worded if "graphics" were replaced by "non-plot graphics". 
 
 
 
EDIT: I have edited my original example to make the  ...

4.7.1.7 Unit tests for Graphics or FE boxes

http://mathematica.stackexchange.com/questions/137541/unit-tests-for-graphics-or-fe-boxes

 
Consider the following expression with bad syntax: 
 
Graphics[{foo}] 
 
 
 
 
How can I detect the error and retrieve the error message programmatically, so I can check for it in unit tests?
