Quaternions


Re Mathematica 6.0 under WinXP.

The code below works as planned, except that a red marker appears between the final ) and ], announcing that more input is expected.  I'm presuming that in this case, the marker can be ignored, but want to doublecheck with others.

Thankx.

w={3,4,5};
u=w/Norm@w;
Quaternion[Cos[Pi/4],Sequence@@(u Sin[Pi/4])]
