    Which textbook is better for engineering students: Kreyszig or Boas?

    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...

    Undergrad How do Unit Vectors Behave in Triangular Coordinate Systems?

    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°?

    Undergrad How do Unit Vectors Behave in Triangular Coordinate Systems?

    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?

    Undergrad How do Unit Vectors Behave in Triangular Coordinate Systems?

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

    Undergrad How do Unit Vectors Behave in Triangular Coordinate Systems?

    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.

    Undergrad Learning the language of math?

    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 Schrödinger equation. I cannot proceed anymore. What are...

    What to study in mathematics after taking basic math courses?

    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.

    Graduate Calculus of Variation - Shortest path on the surface of a sphere

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

    Graduate Calculus of Variation - Shortest path on the surface of a sphere

    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?
