I think I've got some minor braindamage or something but i just can't remember how to find the singular points of(adsbygoogle = window.adsbygoogle || []).push({});

1/(1+z^4)

I guess the problem is to solve the equation 1+x^4=0 and get complex roots but this is what I don't remember how to do. Thanks.
