<Moderator's note: Moved from homework forum for the general question what it means. For the saddle point question, please re-post it in the homework section, but show us some effort and where you stuck.>
I have been given that
and that
Then I am asked to show, by contradiction, that the point (0, 0) is a saddle point for f.
First my problem is that I have never seen that w is a function x and y in the first equation and a function of s and t in the second equation. How can I insert the second equation into the first?
I am not sure if I have provided enough information, but scream out if you miss something.
