@Xavier, version 8 has the bug; since TriangleWave[] was introduced in version 7, testing that as well (by somebody other than you or me) should make for an accurate record.

| Jan 9, 2014 at 4:00 | comment | added | ciao | Interesting question - I've wondered sometimes how MM decides (and why) to not simplify. E.G., 4/Pi (ArcSin[Sin[2/20 Pi]]) results in a trig form, while 4/Pi (ArcSin[Sin[3/20 Pi]]) simplifies, yet both are rationals... | |

It only seems to evaluate when (2 ArcSin[Sin[2 Pi t]])/Pi is an explicit NumberQ
