delta x (a x b) = (b . delta) a - b (delta . a) + a (delta . b) - (a . delta) b(adsbygoogle = window.adsbygoogle || []).push({});

all terms are in vectors, so delta x means curl.

Can anybody prove that?

Because I have tried to prove it, but it keeps failing.

Please help me to figure this out...

Thanks a lot...
