Math Problem Statement
-
f(x, y) = 1 3 x 3 − 3x 2 + y 2 4 + xy + 13x − y + 2
-
f(x, y, z) = x 3 − 2x 2 + y 2 + z 2 − 2xy + xz − yz + 3z
-
f(x, y) = x 3 + y 5 − 3x − 10y + 4
-
f(x, y) = 1 3 x 3 − x − 1 3 y 3 + y
-
f(x, y) = 2x 3 + 4y 2 − 2y 4 − 6x
-
f(x, y, z) = x 2 y − yez + 2x + z
-
f(x, y) = − 1 2 xy + 2 x − 1 y
-
f(x, y) = (x 2 − y 2 )e −(x 2+y 2 )/2
-
f(x, y) = e −(x 2+y 2 ) (x 2 + 2y 2 )
