This article delves into the mathematical principles underlying the rotation of base vectors in a dynamic system. We analyze the behavior of infinitesimal changes, denoted by dψ, as they approach zero, giving insight into the intricate relationship between differentials and vector rotations. By employing limit approaches, we provide a comprehensive understanding of how base vectors rotate and evolve over time in response to these changes, enriching the field of vector calculus and its applications.
