NLineIntegrate

NLineIntegrate[f, {x, y, ...} ∈ curve] computes the numerical scalar line integral of the function f[x, y, ...] over the curve.

• NLineIntegrate[{p, q, ...}, {x, y, ...} ∈ curve] computes the numerical vector line integral of the vector function {p[x, y, ...], q[x, y, ...], ...}.

Examples

NLineIntegrate[1, {x, y} ∈ Circle[]]

NLineIntegrate[x^2 + y^2, {x, y} ∈ Line[{{0, 0}, {1, 1}}]]
