##### 2 Answers

#### Explanation:

A polar coordinate is in the form

This is undefined, but

The polar coordinate is

#### Explanation:

#"to convert from "color(blue)"cartesian to polar"#

#"that is " (x,y)to(r,theta)" where"#

#•color(white)(x)r=sqrt(x^2+y^2)#

#•color(white)(x)theta=tan^-1(y/x)color(white)(x);-pi< theta<= pi#

#"here " x=0" and " y=2#

#rArrr=sqrt(0^2+2^2)=2#

#theta=tan^-1(2/0)larrcolor(red)" undefined"#

#rArrtheta=pi/2#

#rArr(0,2)to(2,pi/2)#
