I am currently looking for suggestions on physics and maths textbooks. The math textbook must cover calculus from the beginning. It can cover multiple subjects, or calculus-only, it does not matter as long as it is clear and easy to understand. The physics textbook must cover high school subjects. Preferably it will continue to cover university-level subjects as well. If one book can not cover both levels of physics subjects, I would be grateful if you could leave suggestions for multiple textbooks which cover high school and university level subjects between them. Thank you.
