I'm having trouble with what should be a simple question!(adsbygoogle = window.adsbygoogle || []).push({});

Leta= (2,4,-2) andb= (4,-2,2)

I need to be able to expressaas the sum of two vectors, one parallel toband the other perpendicular tob.

Thing is, I haven't the foggiest idea where to start! Any ideas?

Thanks
