Question

Maximize/Minimize or Find a root (zero) of derivative

I can use the Maximize function for a finding only a one point.

And I must use the root function (not Maximize) for the creating f function.

Can you help me to use only the Minimize function here.

The problem: root(y(x), x) but Maximize(y, x)

See the picture and the Mathcad-sheet with cloud functions in attach.

Is only a matter of the order of the parameters.

The following works about more than ten times faster than the root version (which seems to be the reason you wanted a maximize version, I think).

Ich bedanke mich herzlich, Werner!

z(x, y) is not equal z(y, x)

Не вызывает случится, с удовольствием, Валерий!

or is it
Не выклікае здарыцца, з задавальненнем, Валерый!

Hope Google translate got it right.
