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.
