WebWe can see from the form in which the gradient is written that ∇f is a vector field in ℝ2. Similarly, if f is a function of x, y, and z, then the gradient of f is = ∇f = fx, y, z i + y, y, z j + z, y, z k. The gradient of a three-variable function is a vector field in ℝ3. Unit vectors may be used to represent the axes of a Cartesian coordinate system. For instance, the standard unit vectors in the direction of the x, y, and z axes of a three dimensional Cartesian coordinate system are They form a set of mutually orthogonal unit vectors, typically referred to as a standard basis in linear algebra. sims 4 kitchen pantry
