The following math commands are being moved to nu-cmd-extra
* cos
* cosh
* egamma
* phi
* pi
* sin
* sinh
* tan
* tanh
* tau

>>Yeah I think this rough separation into "high school" math in extra
and "middle school"/"programmer" math in the core makes a ton of sense.
And to reference the @fdncred list from
