Hello, I have this complex number that I need to convert to polar coord represntation:(adsbygoogle = window.adsbygoogle || []).push({});

z = 1 + j;

the answer is sqrt(2)e^-j45

(45 is degrees).

The part I don't undestand is negative before j45, since a and b are positive, I assumed it's in the first quandrant of Im/Re plane, and if the reference point for theta is real axis postive direction I do not see why there is a "-".

Thanks for explanation.
