Explanation Given information: The provided function is z = 9 − x 2 − y 2 . Formula used: Consider the function z = f ( x , y ) then for the value of ∂ z ∂ x consider y to be constant and differentiate with respect to x and the value of ∂ z ∂ y consider x to be constant and differentiate with respect to y . According to Higher-Order Partial Derivatives, ∂ ∂ x ( ∂ f ∂ x ) = ∂ 2 f ∂ x 2 = f x x ∂ ∂ y ( ∂ f ∂ y ) = ∂ 2 f ∂ y 2 = f y y ∂ ∂ y ( ∂ f ∂ x ) = ∂ 2 f ∂ y ∂ x = f x y ∂ ∂ x ( ∂ f ∂ y ) = ∂ 2 f ∂ x ∂ y = f y x Calculation: Consider the provided function is, z = 9 − x 2 − y 2 Partially derivative of the function z = 9 − x 2 − y 2 with respect to x . z x = ∂ ∂ x ( 9 − x 2 − y 2 ) = 1 2 ⋅ ( 9 − x 2 − y 2 ) − 1 2 ∂ ∂ x ( 9 − x 2 − y 2 ) = 1 2 9 − x 2 − y 2 ⋅ ( − 2 x ) = − x 9 − x 2 − y 2 Partially derivative of the function z = 9 − x 2 − y 2 with respect to y . z y = ∂ ∂ y ( 9 − x 2 − y 2 ) = 1 2 ⋅ ( 9 − x 2 − y 2 ) − 1 2 ∂ ∂ y ( 9 − x 2 − y 2 ) = 1 2 9 − x 2 − y 2 ⋅ ( − 2 y ) = − y 9 − x 2 − y 2 Again, partially derivative of the function z x = − x 9 − x 2 − y 2 with respect to x . z x x = ∂ ∂ x ( − x 9 − x 2 − y 2 ) = − 9 − x 2 − y 2 ∂ ∂ x ( x ) − x ∂ ∂ x ( 9 − x 2 − y 2 ) ( 9 − x 2 − y 2 ) 2 = − 9 − x 2 − y 2 ( 1 ) − x ( − x 9 − x 2 − y 2 ) 9 − x 2 − y 2 = y 2 − 9 ( 9 − x 2 − y 2 ) 3 2 Again, partially derivative of the function z x = − x 9 − x 2 − y 2 with respect to y
