Convert the following complex number in polar form and represent it in Argand Plane:

 

Let

           Equating real and imaginary parts of both sides, we get,

                    

          Squaring and adding these two equations, we get,

                  

Now putting the value of r in equation (1) and (2), we get

                    and

                     and 

Now the value of  such that  and satisfying both the above equation is given by

Hence, 

Which is the required polar form.
