Unseen theorems are theorems that are not explicitly stated or proven in textbooks, but can be deduced or derived using the principles and concepts presented in the text. These theorems require students to apply their understanding of the underlying principles in order to arrive at a conclusion.
One approach to working with unseen theorems is to practice solving problems and proofs that are similar to those presented in the textbook, but with slight variations or modifications. This will help students to build their problem-solving skills and to gain confidence in their ability to apply mathematical concepts to new situations.
In summary, unseen theorems are an important component of mathematics education that help students to develop critical thinking skills and deepen their understanding of the subject matter. By practicing with unseen theorems and working with tutors or study groups, students can build their problem-solving skills and prepare for more advanced study.
