-----------------------+----------------------------------------------------
The integral of abs(cos(x))*sin(x) returns the result as if abs() is
ignored:
{{{
sage: integral(abs(cos(x))*sin(x),(x,pi/2,pi))
-1/2
}}}
while
{{{
sage: numerical_integral(abs(cos(x))*sin(x),pi/2,pi)
(0.49999999999999994, 5.5511151231257819e-15)
}}}
