Matura 2024. jesen - A

Što od navedenoga vrijedi za argumente $\varphi_1$$\varphi_1$ i $\varphi_2$$\varphi_2$ za svaka dva kompleksna broja $z_{1}=r_{1}(\cos \varphi_{1}+i \sin \varphi_{1})$$z_{1}=r_{1}(\cos \varphi_{1}+i \sin \varphi_{1})$ i $z_{2}=r_{2}(\cos \varphi_{2}+i \sin \varphi_{2})$$z_{2}=r_{2}(\cos \varphi_{2}+i \sin \varphi_{2})$ za koje vrijedi $z_{2}=-z_{1}$$z_{2}=-z_{1}$?
