We describe how we can find the singed area bounded by a parametric curve with respect to a slanted line y = mx + b in two dimensions. We extend this idea to the corresponding setting in three dimensions. These are special cases of Green’s Theorem and the Divergence Theorem, but the ideas and methods introduced here are accessible to a wider audience.
