AI Thread Summary
Squaring a vector is not a defined operation, as there is no specific multiplication method for vectors. Instead, the dot product serves as a way to generalize multiplication for vectors, allowing one to compute the squared norm by taking the dot product of a vector with itself. This results in the sum of the squares of each component of the vector. Some users express confusion regarding calculations, particularly when factors like sin(θ) are involved. Clarifying the specific problem and attempts can help in resolving discrepancies in answers.

How do you sqaure a vector?

Is it the magnitude of the vector times the vector?
 
Mathematics news on Phys.org
You can't "square" a vector, because there's no distinct "multiply" operation defined for vectors.

The dot product is a generalization of multiplication to vectors, and you can certain take the dot product of a vector with itself. The resulting quantity is the squared norm of the vector.

would this mean just the square of each term added together?

ive tried this but then end upwith an answer different to the one given, i have a factor of sin($) missing.

Maybe if you state the question, and your attempts at the question, then it may be possible to answer you.
 

Thread 'Non-orthogonal bases'

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...

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

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...
