Describe gradient of a scalar field
WebThis gives an important fact: If a vector field is conservative, it is irrotational, meaning the curl is zero everywhere. In particular, since gradient fields are always conservative, the curl of the gradient is always zero. That is a … WebThe first of these conditions represents the fundamental theorem of the gradient and is true for any vector field that is a gradient of a differentiable single valued scalar field P. The second condition is a requirement of F so that it can be expressed as the gradient of a scalar function.
