@gerryliyana solve for RHS first by using the values of dimensional vectors given in question

electrokid Group TitleBest ResponseYou've already chosen the best response.3
\[\vec{a}\times\vec{b}=\left\begin{matrix} \hat{x}&\hat{y}&\hat{z}\\ u&v&0\\ x&y&0 \end{matrix}\right =\hat{z}(uyvx)\\ \vec{a}\cdot\vec{b}=ux+vy\\ ab = (u+iv)(x+iy)=ux+i(vx)+i(uy)+(i^2)(xy) \]

myko Group TitleBest ResponseYou've already chosen the best response.0
are you sure it's right? Because: a.b=ux+vy iz(axb)=i(uyxv) and a*b=uxvy+i(uy+vx) so it is not equal: uxvy+i(uy+vx) =/= ux+vy+i(uyxv)

electrokid Group TitleBest ResponseYou've already chosen the best response.3
\[ab=(uyvx)+i(vx+uy)\]
 one year ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.0
its same with my answer @myko
 one year ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.0
yeah i think so
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.3
\[ab=\hat{z}\cdot(\vec{a}\times\vec{b})+i(\vec{a}\cdot\vec{b})\]

myko Group TitleBest ResponseYou've already chosen the best response.0
vx+uy =/= a.b @electrokid
 one year ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.0
so what the right answer??
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.3
oh yea.. my bad..
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.3
that "*" in the question must be a complex conjugate
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.3
then it seems you might have it right.
 one year ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.0
good idea!! oh my bad...,
 one year ago

gerryliyana Group TitleBest ResponseYou've already chosen the best response.0
yeah,"*" means conjugate
 one year ago

electrokid Group TitleBest ResponseYou've already chosen the best response.3
always make sure that people are talking the same math language

thank you @electrokid

niksva Group TitleBest ResponseYou've already chosen the best response.0
@electrokid if "*" is complex conjugate then it will be rightly solved
