WebJul 14, 2016 · Gradient is covariant. Let's consider gradient of a scalar function. The reason is that such a gradient is the difference of the function per unit distance in the direction of the basis vector. We often treat gradient as usual vector because we often transform from one orthonormal basis into another orthonormal basis. WebApr 8, 2024 · The Gradient vector points towards the maximum space rate change. The magnitude and direction of the Gradient is the maximum rate of change the scalar field with respect to position i.e. spatial coordinates. Let me make you understand this with a simple example.
