RE: MAX command
The Function app currently relies on the differentiating functionality of the CAS for extrema finding. I might add (NOTE: as has been said before, I'm not speaking for HP: there are no guarantees towards future releases or improvements etc.) a numerical extrema finder for Function / Fcn / Plot / Extremum. The CAS doesn't currently like differentiating MAX.

One possible workaround is to define V1 in the Advanced Graphing app as 0.5*(X+Y+ABS(X-Y)) and then define F1 as V1(SIN(X),COS(X)). Then try using Function / Plot / Fcn / Extremum (the CAS is more likely to differentiate ABS). This workaround also helps with Fcn / Slope and Fcn / Tangent (the CAS is similarly used for differentiation for these features).
