SUMMARY

The discussion centers on the mathematical operation of dividing vectors in the context of dot products. It clarifies that the dot product of two vectors results in a scalar, not a vector, and thus division of vectors as fractions is not valid. For example, given vectors a = (1,2) and b = (3,4), the dot product a · b equals 11, which is a scalar. Therefore, the expression a · a / b · a does not yield a vector but rather a numerical value.

PREREQUISITES
  • Understanding of vector operations, specifically dot products.
  • Familiarity with scalar and vector distinctions in linear algebra.
  • Basic knowledge of vector notation and operations.
  • Ability to perform arithmetic operations with vectors.
NEXT STEPS
  • Study the properties of dot products in vector algebra.
  • Learn about vector normalization and its applications.
  • Explore the concept of vector division and its limitations.
  • Investigate other vector operations such as cross products and their geometric interpretations.
USEFUL FOR

Students studying linear algebra, mathematicians, and anyone interested in understanding vector operations and their applications in physics and engineering.

Homework Statement


can you divide 2 vectors which are in fractions?


Homework Equations


example a . a / b . a (dot products)


The Attempt at a Solution


would it become a / b?
 
Physics news on Phys.org
a and b are vectors?
If so then a dot a and a dot b are not vectors, just numbers.
Example: a = (1,2) b = (3,4)
Then a dot b = 1*3 + 2*4 = 11
