Some questions about linear transformation

AI Thread Summary
A linear transformation is defined as a special type of function that satisfies specific properties, namely T(cu + dv) = cT(u) + dT(v) and T(cu) = cT(u) for all vectors u, v and scalars c, d. The superposition principle describes how linear transformations can be expressed as a linear combination of inputs and their corresponding outputs, reinforcing the linearity of the system. The discussion seeks clarification on these concepts, confirming the accuracy of the statements made about linear transformations and the superposition principle. Participants are encouraged to provide further insights or improved explanations. Overall, the thread emphasizes understanding the foundational principles of linear transformations in linear algebra.

Hi Ho! ^^v

I've some questions regarding linear transformation in my linear algebra course, guys!
Please help me! ^^v

Statement: A linear transformation is a special type of function.

My answer: Yes, it is a special type of function because it must satisfy the following properties from the definition of linear transformations which is
A transformation (or mapping) T is linear if:
1. T(c u + d v) = c T(u) + d T(v) for all u, v in the domain of T;
2. T(c u) = c T(u) for all u and all scalars c.

Am I right?

Statement: The superposition principle is a physical description of a linear transformation.
Note: In my book it is written, I rephrased it, the superposition principle is defined as the generalization of the definition of linear transformation (i.e. T(c1 v1 + ... + cp vp) = c1 T(v1) + ... + cp T(vp) for v1...vp in the domain of T and c1...cp are scalars)

My answer: Yes, it is because a physical event can be determined to be linear if the "input" conditions can be expressed as a linear combination of such "input" and the system's response is the same linear combination of the responses to the indiviual "input".

Am I right?

Maybe you could provide me with a better answer, please? ^^

Thank you very much, guys!
Any help would be appreciated! ^^v

Yes, you are correct. Sorry you had to wait 12 years for an answer.
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...
