Bug? int(abs(sin(2*pi*x)),x=0..1) [SW 8151] - Snorre - 12-04-2015 04:26 PM
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.

Not reported anywhere I've seen. Thanks! Have passed it on. |
