mathcad: minimum function to 2 variables

[Benn]

Hello everyone!
I am performing the minimum of a function in two variables, say f(x,y), where x and y are two corners. I write given and then insert two test values of x and y, then minimize with sol:=minimize(f,x,y) and get me the x and y corners that minimize the function.
I realized, however, that if I change the test values with other random values, also x and y change and therefore also changes the minimum value of the function. I don't think that's normal. Can you help me?
Thank you! !

and the presentation? and the rules? ? ?
All right, save yourself for the little prince. .

I don't know what you mean by test values. f function should be independent of these values, right?

I don't know mathcad, but if you try to post the function I can do a matlab test.

you can also solve the equation given by the equal gradient to zero and see if you get the same result.

Sorry I didn't show up earlier.
cmq function depends on these variables.
the test values would be two random values of the variables...and from what I understood are necessary to use the applications "given","find" and others.. .

Yes, but what is the function?
I'm sorry, but I'm not mad at mathcad.
