hi

given such system of equations

##

\begin{cases}

\rho^2 = 2 \rho \\

2\theta= -\theta+2k\pi , k\in \mathbb Z \\

\end{cases}

##

in the solution of the professor the system is solved is solved as follows.

##

\begin{cases}

\rho=0 , \rho=2 \\

\theta= -\frac 2 3 k\pi , k = 0,1,2 \\

\end{cases}

##

isn't that minus in front of 2/3 an error?

because it should be positive, right ?
