I have a vector(adsbygoogle = window.adsbygoogle || []).push({}); v= ai+bxj

Now I want to finda.So I apply chain rule and differentiate dv/dx * dx/dt = bj* Vx= bj*ai??

Now what does this mean? Is this allright? Should I not care about the vector directions when differentiating and just use the magnitudesa= ab , if yes then why? And what will be the direction of the acceleration then?
