Curl free field

WebThe curl of a gradient is zero Let f ( x, y, z) be a scalar-valued function. Then its gradient ∇ f ( x, y, z) = ( ∂ f ∂ x ( x, y, z), ∂ f ∂ y ( x, y, z), ∂ f ∂ z ( x, y, z)) is a vector field, which we denote by F = ∇ f . We can easily calculate that the curl of F is zero. We use the formula for curl F in terms of its components WebYou can think of it like this: there are 3 types of line integrals: 1) line integrals with respect to arc length (dS) 2) line integrals with respect to x, and/or y (surface area dxdy) 3) line …
