The discussion centers on the mathematical concept of the product of the magnitudes of two vectors, specifically vectors AC and BD. Participants clarify that the original question does not involve a dot product, but rather the expression |AC| * |BD|. It is concluded that without additional information, such as the angle between the vectors, the problem is unsolvable as varying the magnitude of one vector while keeping the other fixed leads to multiple possible outcomes.
PREREQUISITESStudents and professionals in mathematics, physics, and engineering who are dealing with vector analysis and require a deeper understanding of vector operations and their implications.
No, the question really states: ##|\vec{AC}| .| \vec{BD}|## so I interpret it as product of magnitude of vector AC and BDharuspex said:Your question as stated does not involve a dot product. Did you mean ##|\vec{AC}.\vec{BD}|##?
Oh ok, I see your point.Also, as stated, it clearly is unsolvable. You could easily vary |AC| while keeping |BD| fixed. Not sure yet if changing it to the dot product of the vectors resolves that.
