Line integral of a line segment
NettetOur notation for line integrals is one of several common notations. This notation's strength is that it emphasizes the role of a vector field and dot product. Another common notation for the line integral of a vector field P, Q, R along a curve C is . ∫ C P d x + Q d y + R d z. This notation is common in physics and engineering. NettetLine integrals are useful in physics for computing the work done by a force on a moving object. If you parameterize the curve such that you move in the opposite direction as t t increases, the value of the line …
