let y(adsbygoogle = window.adsbygoogle || []).push({}); _{1}=(1,0,i,0) and y_{2}=(0,i,1,0)

what is (y_{1}.y_{2})/(y_{1}.y_{1})?

I make it i/(1+i^{2}) = i/0 which seems incorrect.

My notes seem to give the answer as -i/2 and I don't understand how this was calculated.

Any help is appreciated. Thanks
