The video tutorial explains how to find a potential function for a given vector field by verifying its conservativeness. It demonstrates the process of checking partial derivatives to confirm the field is conservative. Once confirmed, the tutorial guides through integrating components to determine the potential function. Finally, it applies the fundamental theorem of line integrals to evaluate the line integral along a specified curve using the derived potential function.
