I can't figure out how they get i/sqrt(2) for normalisation of c1. Why is it a complex number? If I normalise c1 I just get 1/sqrt(2) because i disappears in the absolute value squared.

Thanks

It looks like you left out other information from the problem, but apparently, there was the relation $c_1 = i c_0$. That's where the $i$ comes from. Note that you had to have this relationship to solve for $c_0$
otherwise you'd have two unknowns but only one equation.

There was this relation:

Aha, so the exponential is also interpreted as i then. Thanks, got it!

$e^{i\pi/2}= \cos (\pi/2) + i \sin(\pi/2) = i$
$e^{iv}= \cos (v) + i \sin(v)$
