True-False Determine whether the statement is true or false. Explain your answer. In these exercises, assume that \(f(x, y)\) has continuous second-order partial derivatives and that
\(D(x, y)=f_{x x}(x, y) f_{y y}(x, y)-f_{x y}^{2}(x, y)\)
If the function \(f\) is defined on the disk \(x^{2}+y^{2} \leq 1\), then \(f\) has a critical point somewhere on this disk.
