You should know, that to download a word document from unknown origin is a big hurdle not many of us want to risk. Definitely not me, as I additionally consider it as bad behavior to force me to take action rather than trying to concentrate on help. But this is my personal attitude towards users who don't take the effort of posting their questions adequately while simultaneously demanding efforts from others. I think you should know this and consider to type in the entire question instead. We have a LaTex library in place that helps a lot to even type in complicated formulas.Dyatlov said:Hello.
I would like to check my understanding of how you transform the covariant coordinates of a vector between two bases.
I worked a simple example in the attached word document.
Let me know what you think.
A covariant vector is a mathematical object that represents a physical quantity and transforms in a specific way under coordinate transformations. It is also known as a contravariant vector and is denoted by a superscript index, such as vi.
The purpose of a worked example on a covariant vector transformation is to demonstrate how a covariant vector changes when the coordinate system is transformed. This helps to understand the concept of covariant vectors and how they behave under different coordinate systems.
A covariant vector is transformed using the chain rule in multivariable calculus. This involves multiplying the vector by a Jacobian matrix, which contains the partial derivatives of the new coordinates with respect to the old coordinates. The result is a new covariant vector in the new coordinate system.
A covariant vector transforms in a specific way under coordinate transformations, while a contravariant vector transforms in the opposite way. This means that their components have different transformation rules, with covariant vectors using the chain rule and contravariant vectors using the inverse of the Jacobian matrix.
Covariant vectors are important in physics because they represent physical quantities, such as velocity, momentum, and force, in a way that is independent of the coordinate system. This allows for easier calculations and analysis of physical phenomena, as well as a more intuitive understanding of the underlying mathematical concepts.
