Line Integral of a Scalar Function

This example demonstrates the calculation and visualization of a line integral of a scalar function along a curve. Key math concepts include line integrals, scalar fields, and curve parameterization. It uses GeoGebra commands like CurveCartesian for curve creation and Surface for scalar function visualization, with objects c, f, C, C', I. Suitable for high school students and above, particularly those studying calculus to understand the geometric interpretation and computation of line integrals.
