if you mean i/(i+1) , the answer is;
\(\sqrt{-1}/(\sqrt{-1}+1)\)
now, multiply each side with \((\sqrt{-1}-1)\)
you will get \((-1-\sqrt{-1})/(-1-1)\)
that is \((-1-\sqrt{-1})/-2\)
get rid of the ((-)) ; the answer is most basic this;
\((1+\sqrt{-1})/2\)
\((1+i)/2\)
if you mean (i/i)+1, that is 1+1=2 -_-
