This repository contains a database of questions on Integration Techniques, part of the MathE project (https://mathe.ipb.pt/), a mathematics teaching platform that offers personalized and dynamic learning paths for each student. The platform has 1849 students distributed across 72 universities in 27 countries, and has a total of 1874 questions registered, covering various topics and subtopics that cover the entire range of higher education content. The database consists of questions and supporting materials, such as links to videos and PDF files, with the aim of facilitating the learning process. This set of information can be used both for training Large Language Model (LLM) and Retrieval-Augmented Generation (RAG), as well as for advances in the development of intelligent and adaptive platforms.
