Nettet7. sep. 2024 · Figure : Stokes’ theorem relates the flux integral over the surface to a line integral around the boundary of the surface. Note that the orientation of the curve is positive. Suppose surface is a flat region in the -plane with upward orientation. Then the unit normal vector is and surface integral. Nettet2. Actually, the line integral for a vector field is a scalar, not a vector. It's a dot product of the vector evaluated at each point on the curve (a vector) with the tangent vector at that point (also a vector). This is the correct definition for the work done by an object moving along the curve, as work is a scalar. – Dylan. Nov 6, 2014 at ...

NettetI understand what is going on visually/geometrically speaking with the line integral of a scalar field but NOT the line integral of a VECTOR field. Just looking at Vector fields before doing line integration on them, they actually take up the entire R^2 or R^3 space so how one can justify visually with some arrows which actually have space between … NettetA line integral (sometimes called a path integral) of a scalar-valued function can be thought of as a generalization of the one-variable integral of a function over an interval, where the interval can be shaped into a …
