Developed a comprehensive steady-state reaction-diffusion example for the mphowardlab/essential-math repository, focusing on both mathematical derivation and visual representation to enhance educational resources. The work involved applying differential equations and mathematical modeling to construct a clear, instructive demonstration, with technical writing used to document each step for user clarity. Python was utilized for numerical methods and data visualization, while Markdown and SVG supported the creation of accessible documentation and graphics. This feature aligned with the project roadmap by broadening the library’s instructional scope, improving onboarding for new users, and providing researchers and students with a practical, well-documented PDE example.
