Why we study Dot product and cross product ??
Answers
Answer:
There are a lot of applications of real life dynamical systems in physics where vector analysis is of crucial importance.
The most basic of all is the system having multiple force vectors.
For it's analysis over finding out the reusltant vector or finding out the components of one force vector over some other vector requires us to use dot as well as cross products. which help us evaluating overlapping fields due to each of these multiple pairwise forces.
A lot of applications of vectors when carried forward to the idea of tensors is of crucial importance for Better Mathematical analysis of a significantly difficult system posed as a problem.
Hope this helps you and was convincing enough to you ! ｡◕‿◕｡
Answer:
It says dot product actually gives us a way to depict mathematically how parallel two lines are and on the other side cross products tells us how two lines are perpendicular to each other.
