(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

If you have two functions dependent on t, A(t) and B(t). Prove their derivatives are as follows:

d(A (dot) B) / dt = [A (dot) (dB)/(d(t)] + [d(A)/d(t) (dot) B]

{Where "(dot)" acts as the dot product}

d(A x B) / dt = [A x (dB)/(d(t)] + [d(A)/d(t) x B]

{Where "x" acts as the cross product}

I have little experience with differentiating cross products and dot products and appreciate any help in starting this one!

Thanks,

Janet
