If (a,b) is a are the coordinates of a point in Cartesian Plane, u is its magnitude and α is its angle then (a,b) in Polar Form is written as (u,α).
Magnitude of a cartesian coordinates (a,b) is given bya2+b2 and its angle is given by tan1(ba)

Let r be the magnitude of (3,1) and θ be its angle.
Magnitude of (3,1)=(3)2+12=3+1=4=2=r
Angle of (3,1)=tan1(13)=π6

Angle of (3,1)=π6=θ

(3,1)=(r,θ)=(2,π6)
(3,1)=(2,π6)
Note that the angle is given in radian measure.
