The given example shows the features of the application of the mathematical apparatus of geometric modeling of the field in normal conic coordinates. WebSal says that in order to represent the vector field as the gradient of a scalar field, the vector field must be conservative. That a vector field is conservative can be tested by obtaining the curl (𝛁⃗⨉F⃗) of the vector field; if it's 0, then the field is conservative. earnshaw\u0027s infants\u0027 department
