  skos:definition """In mathematics, a <b>line integral</b> is an integral where the function to be integrated is evaluated along a curve.  The terms <i>path integral</i>, <i>curve integral</i>, and <i>curvilinear integral</i> are also used; <i>contour integral</i> is used as well, although that is typically reserved for line integrals in the complex plane.
<br/>The function to be integrated may be a scalar field or a vector field. The value of the line integral is the sum of values of the field at all points on the curve, weighted by some scalar function on the curve (commonly arc length or, for a vector field, the scalar product of the vector field with a differential vector in the curve). This weighting distinguishes the line integral from simpler integrals defined on intervals.
