Contributed to the sympy/sympy repository by improving Laplace transform correctness and enhancing documentation for differential equation solving. Addressed exponential term handling in Laplace transforms for polynomial expressions and updated the inverse Laplace transform to return results multiplied by the Heaviside function, ensuring mathematical accuracy and adding regression tests for reliability. Developed a comprehensive Laplace Transform ODE/PDE Solving Guide within the documentation, clarifying Heaviside handling and streamlining user onboarding. Additionally, revised the bug reporting workflow to reflect a more integrated process. Work involved Python, SymPy, and Markdown, with a focus on symbolic computation, technical writing, and robust testing practices.
