O Prove that the function f(x, y) = (x² + y²)e-(x²+y²) has infinitely many critical points and classify them. Guidance: After finding all the critical points, identify an expression in f(x, y) which repeats itself, denote it by t and investigate the function as one variable function. Afterwards, induce your findings from the one variable function to the original function.

O Prove that the function
f(x, y) = (x² + y²)e-(x²+y²)
has infinitely many critical points and classify them.
Guidance: After finding all the critical points, identify an expression in f(x, y)
which repeats itself, denote it by t and investigate the function as one variable
function. Afterwards, induce your findings from the one variable function to the
original function.
