WebThe line integral of the scalar field, F(t), is not equal to zero. The gradient of F(t) will be conservative, and the line integral of any closed loop in a conservative vector field is 0. … WebContour integration is a method of evaluating integrals of functions along oriented curves in the complex plane. It is an extension of the usual integral of a function along an interval in the real number line. Contour integrals may be evaluated using direct calculations, the Cauchy integral formula, or the residue theorem.
