Hello I want to demonstrate a equation of Vector image on another vector (A on B) So i go this steps and as we know so change the equation but in my equation A is (vector scale) not a (Vector)!!!! what is my problem?
You have [itex]\overline{A}[/itex], [itex]A[/itex], and [itex]\left|\overline{A}\right|[/itex]. I understand that [itex]\overline{A}[/itex] is a vector and that [itex]\left|\overline{A}\right|[/itex] is its length but what is [itex]A[/itex]?
Thanks for your replay A and |A| both of them are length of A vector (in electromagnetic books we assume that A=|A| for easy to write)
I rewrite the Steps. main formula: steps: as we know and so but in my equation |A| is (vector length) not a (Vector)!!!! what is my problem?
Oh Baby, What are you doing? You are taking the dot product of vector A and vector B which results in a scalar. Then you are taking the dot product of that scalar with vector B. That makes no sense. I think you want the dot product of vector A and vector B/|B|. B/|B| is the unit vector in the B direction. Ratch
Thanks friends i found my probelm Image of Vector of A on B is a Vector and we should define the direct of it when write the image equation
