Not always true.
For example, define:
f(x,y) = xy(x² − y²) / (x² + y²) for (x,y) ≠ (0,0),
and f(0,0) = 0.
Then at (0,0):
∂²f / ∂y∂x = −1
but
∂²f / ∂x∂y = 1
So the order of partial derivatives does matter in general.
They are equal only if the function is smooth enough (i.e. second derivatives are continuous : Clairaut/Schwarz theorem).
Also, this result is usually attributed to Clairaut,
not Euler.
