Maximum of a two variables function

Hello,

Could anyone help me with an example of the syntax to calculate the maximums and minimums of a two variable's function f(x,y) over an interval x [-0,100], y [0,100]. I've unsuccessfully

tried different options.

Thanks in adavance!

Hello alfabeta2, you plot a two variable's function, but you don't include the calculation of its maximum and minimum points.

Hello,

perhaps you find this in https://www.geogebra.org/ma...

Thanks @Roman Chijner. It was a general question. I was asking if there's is a way in Geogebra to calculate the maximums and minimums of a two variable function.

Something like Maxium(f(x,y),[0,1],[0,1])

Hi,

There are various commands for the one-dimensional function. For two-dimensional, there is no.

For example, in https://www.geogebra.org/ma..., you can study, using Extrema lines, the problem of finding these extremes.
