During May 2025, Logan Wood contributed to the mphowardlab/essential-math repository by developing a new feature that introduces the triple product rule in multivariable calculus, specifically contextualized for thermodynamics applications such as heat capacity. Logan approached the task with a focus on mathematical rigor, providing a detailed derivation and integrating a practical example to enhance learner comprehension. The work emphasized technical writing and documentation, utilizing Markdown to clearly present the derivation and its application. By updating contributor credits and leveraging version control with Git, Logan ensured both technical depth and collaborative transparency in the enhancement of the repository’s core calculus content.
