SOLUTION

TO DETERMINE

The polar coordinates whose cartesian coordinates are

 \displaystyle \sf{ \bigg(0 \: , \frac{1}{2}  \bigg)}

EVALUATION

Let (r, θ) be the polar coordinates of the point

Then

 \displaystyle \sf{ 0  = r \cos \theta \: \: , \frac{1}{2}  =r \sin \theta}

Now Squaring and adding we get

 \displaystyle \sf{  {r}^{2}  =  \frac{1}{4} }

 \displaystyle \sf{   \implies \: r  =  \frac{1}{2} }

Again

 \displaystyle \sf{  tan \theta =  \frac{ \displaystyle \sf{ \frac{1}{2}} }{0} }

 \displaystyle \sf{   \implies \: tan \theta =   \infty }

 \displaystyle \sf{   \implies \: tan \theta =   \infty }

 \displaystyle \sf{   \implies  \theta =    \frac{\pi}{2}  }

Hence the required polar coordinates

 \displaystyle \sf{ \bigg( \frac{1}{2} \: , \frac{\pi}{2}  \bigg)}
