Hello,
Maybe this was reported somewhere already (didn't find a posting).
When evaluating int( abs(sin(2*pi*x)), x=0..1 )
I get the incorrect result 0.
This doesn't occur when using cosine: int( abs(cos(2*pi*x)), x=0..1 ),
or by rewriting the expression: int( abs(sin(x)), x=0..2*pi )/(2*pi);
both yield 2/pi.
