Boas is much more better than kreysizg. Last time during my degree, kreysizg was used for my engineering course. Engineering Maths is very hard compare to calculus. The advanced engineering maths by kreysizg did'nt help much in my study and understanding. Boas is very different. Even though I...

Hi ZapperZ, thanks for the recommendations, there are 16 chapters in the book, which chapters should I focus for the mathematics of Quantum Mechanics?

I'm reading "An Introduction to Tensors for Students of Physics and Engineering" I cannot understand in the triangular coordinate systems, how i and i* now meet at an angle of 60°?

each unit vector parallel to each axes? if I have three unit vector u, v ,w, and axes x , y, z , then u parallel to x , v parallel to y , w parallel to z?

Does it mean that the vector is parallel to the axis?

How does it look like if three unit vectors at a point such that each vector is tangent to one of the axes in 3-Dimensional Cartesian System? Can anyone illustrate about this? Thanks.

I have problem with the maths for quantum mechanics too. I am using the book "Introduction to Quantum Mechanics 2nd edition, David J.Griffiths". I stuck in the chapter 2 where there are two methods to solve the Simple Harmonic Motion using Schrodinger equation. I cannot proceed anymore. What are...

Hi ZapperZ, Is there any guide for self-study for Physics for preparation for Physics course(Bachelor Degree/Master) in future? I have already take the subject General Physics 1 & General Physics 2 before. Thanks.

Thanks for your advice. Actually I'm a engineer, the highest level of maths I have studied is engineering maths and numerical analysis. This is my first time heard about topology and manifold.

Is there any basic knowledge I need to know before studying differential geometry?

Hi jgens, can you recommend any books for differential geometry for beginner?

Okie, I get it, many thanks for explaining.

I have another question, why the solution comes out is an equation of a plane and not an equation of a ring(circle)?

Thanks PAllen.

Am I right to say that the intersection of a plane through the center of a sphere is a ring(circle), and the short arc of this ring(circle) which pass through the two points is the shortest path?
