For some reason, in nodeeditor, in math node, sin[...] not longer functions properly, but sin(...) does function correctly,
in BOTH MoI V4, and MoI V5beta.

Possible culprits?:
a. Windows 11 upgrade did something.
b. MoI V5beta did something? But to both V5beta and V4.
c. ?

Nodeeditor was not changed by myself...except I did replace arraysExt.js from here:
https://moi3d.com/forum/index.php?webtag=MOI&msg=10671.2

The attached nod program has both [...] and (...) versions of SineWave built with nodes.

Perhaps someone who has not upgraded to Windows 11, or MoI V5beta could try the node program, in MoI V4?
