Convert the complex number  in to polar form.

 

We can simplify the given complex number in  form as follows:

      

          Let,

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

         

Squaring and adding, we get,

         

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

         

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

Hence,        

Which is the required polar form.
