Dear fellow developers,
I've encountered a really strange result in Sage while using Maxima.
|
sage:f(x,y)=(x^2-y^2)/(x^2+y^2)^2
sage:integrate(integrate(abs(f(x,y)),x,0,1),y,0,1)
-1/4*pi
|
This is really weird. At least, the result should be positive! SymPy
however yields the correct result:
|
sage: |integrate(integrate(abs(f(x,y)),x,0,1,
algorithm='sympy'),y,0,1||||, algorithm='sympy'||)|
+Infinity
||
|
What is the issue here? Did I do something wrong, or is this a bug with
Maxima?
Best
Michael
