Periodacity 对比 Mathematical Proofs 的使用情况和统计数据

A collection of mathematical proofs, definitions, theorems, and identities serving a purpose not only for students to study and understand the mathematical truths taught in the classroom, but to develop an insight as to how these truths are observed and are logical by their nature. The app currently contains 70 of these, however in future versions, more will be included along with more features.
