Find the Jacobians of the functions. If x, y, and z are continuous functions of u, v, and w with continuous first partial derivatives, then the Jacobians J(u, v) and J(u, v, w) are defined as: |∂x/∂u ∂x/∂v ∂x/∂w|J(u, v) = |∂x/∂u ∂x/∂v| J(u, v, w) = |∂y/∂u ∂y/∂v ∂y/∂w| |∂y/u ∂y/∂v| |∂z/∂u ∂z/∂v ∂z/∂w|
