1) Note that we'll make use of the following formulas:
[tex]\begin{gathered} r^2=x^2+y^2 \\ r^2=3^2+0^2 \\ r^2=9 \\ \sqrt[]{r}=\sqrt[]{9} \\ r=-3,3 \\ r=3 \end{gathered}[/tex]
So the radius according to the text must be positive, so we can discard the negative value.
2) Now the angle theta:
[tex]\tan (\theta)=\frac{y}{x}=\frac{0}{3}=Undefined[/tex]
Since this is undefined, we can state that
3) So we can state the Polar Coordinates as:
[tex]P(3,0)[/tex]
