New issue 3220 by [email protected]: Integrating Borwein integrals hangs
http://code.google.com/p/sympy/issues/detail?id=3220
I recently stumbled upon on Borwein Integrals -
http://mathworld.wolfram.com/BorweinIntegrals.html and for some fun
background see also
http://mathoverflow.net/questions/11517/computer-algebra-errors/11607#11607
And I decided to see how it fares in Sympy:
In [1]: timeit(integrate(sin(x)/x * 3*sin(x/3)/x, (x, 0, oo)))
10 loops, best of 3: 142 ms per loop
In [2]: timeit(integrate(sin(x)/x * 3*sin(x/3)/x, (x, 0, oo)))
10 loops, best of 3: 142 ms per loop
In [3]: timeit(integrate(sin(x)/x * 3*sin(x/3)/x * 5*sin(x/5)/x, (x, 0,
oo)))
And now my machine seems to keep twiddling its digital thumbs at 100% of
CPU for a bit too long...
