Studying Self-Studying Physics in 8 months for a University Entrance Exam
The first eight chapters of Boas encompass the math requirements in the syllabus entirely. You can definitely cover that much in eight months if you already know single variable calculus. However, I doubt that you could cover the other material in that time, even at the level of Halliday and...- Zexuo

Other Math Physics Resource Request: Mary L Boas Book
I've found different presentations of the same material helpful on occasion. For instance, I recall feeling like Boas's PDE chapter skipped an important detail early on, so I worked through the PDE chapter in Boyce/DiPrima first. I then picked up where I left off with Boas without my earlier...- Zexuo

Confused about calculating the average energy from a distribution graph
If I read you correctly, you don't deal directly with the probabilities here, but with the counts. p(E_i) = count(E_i) / SUM[count(E_i)]- Zexuo

Can You Help Solve This Generalized Work Problem with an Illustrative Image?
You can express h1 - h2 in terms of L and theta. Part b will have a term for the spring energy at maximum compression on the final side.- Zexuo

Vector calculus — Computing this Divergence
$$\nabla\cdot\mathbf{F} = \lim_{V\rightarrow 0}\frac{1}{V}\oint_S\mathbf{F\cdot n}da$$ $$\nabla\times\mathbf{F} = \lim_{V\rightarrow 0}\frac{1}{V}\oint_S\mathbf{n\times F}da$$ No coordinate system needed... until you want to solve a problem.- Zexuo

Studying What to do in a gap year to prepare for a Physics + Math degree
With a restricted timeline you might want to switch to Boas for linear algebra and multivariable calculus. She covers those topics in the early chapters. Since you plan to major in math as well you'll take a complete linear algebra course at some point but Boas gives you enough to proceed with...- Zexuo

Studying What to do in a gap year to prepare for a Physics + Math degree
Overall, the Thomas calculus textbook will likely mirror the beginning calculus course better. Read it through and do all the odd or even numbered exercises. If you have the time do all of them. Same with physics text. If you already know Python, learn to use the numpy, scipy, matplotlib, and...- Zexuo

Programs Should I become a physicist or a mathematician?
I would echo Choppy's comments. I would add that, if the physics department has a "math methods" course, you may prefer to take the courses in the math department covering the topics in that course, even if you end up pursuing physics. Ask your advisor about that option.- Zexuo

Resources for self-studying PDEs
Assuming you've diagnosed the problem correctly, you already have a handle on the derivation of the Laplacian in Cartesian, cylindrical, and spherical coordinates, separation of variables in PDEs, Fourier series, and solving PDEs with rectangular symmetry. Vis à vis PDEs, Legendre and Bessel...- Zexuo

Studying Focus on in-depth understanding of the Maths behind Physics
I consider a mathematical method understood once I've followed the proof for it step by step, noting the techniques involved. I find it helpful in holding the method in mind or, failing that, deriving it from more basic principles when needed.- Zexuo

Other Rebuilding Physics Knowledge: Tips for Returning to the Field after a Hiatus
My method of recovering undergraduate physics knowledge, reading the textbooks from the foundational courses and solving all the problems, may not fit your desired timeline. Then again, I had much more time away from it than you do and needed to start from my calculus textbook, which alone took...- Zexuo

Preparing for a Physics Degree: The Role of Programming in High School
If you feel comfortable with Python, learn numpy, scipy and matplotlib as jedishrfu mentioned above. You might find sympy handy and you don't need to delve very deeply into pandas and scikit-learn before putting them to use with lab data.- Zexuo
