Hello. I am a high school student wishing to self study physics. I am just seeking some advice on the textbooks that I should use for both physics and the accompanying mathematics. For calculus, I already have some background knowledge based on previous readings of Stewart's book, but I would like to study calculus thoroughly this time. What textbook should I use? As for physics, it is a similar situation with regards to the background knowledge. Should I start with a general calculus-based textbook such as Halliday and Resnick or University Physics? And if so, which one should I use? Thank you.
