I.6.2. Decomposition of a vector along two given directions

📚

Decomposition of a vector along two given directions Δ1 și Δ2 it is done as follows:

  • From the top of the vector go parallel to the two given directions.

  • We write the vectorial equation:



  • We write the scalar equation:


🔦 Remark

The decomposition of a vector along two given directions is the opposite of the composition of two nonlinear and with the same application point vectors, with the parallelogram rule.
