Worked on the geogebra/manual repository to enhance documentation accuracy and clarity, focusing on improving the user experience for mathematical content. Addressed issues such as typos, formatting inconsistencies, and outdated resource links, ensuring that documentation is both reliable and easy to follow. Standardized mathematical notation by applying control sequences for sine and cosine, which improved consistency across the documentation. Utilized Markdown and adoc to implement these changes, drawing on skills in content management, technical writing, and mathematics. The updates support faster onboarding and reduce support questions by making the documentation more trustworthy and accessible for both new and experienced users.
