Vektorové důkazy geometrických nerovností
Rozhledy matematicko-fyzikální, Tome 86 (2011) no. 4, pp. 3-12
First, the article mentions basic characteristics of the dot product of two vectors in a plane or in a space, and the implementation of the dot product in a contemporary grammar school textbook. Then, the work focuses on the solution of more demanding problems where the dot product of vectors is effectively applicable, although the operation is not mentioned in the problem statement.
