Expert Answer:


Now, Let, 
Equating real and imaginary parts, we get,
Squaring and adding, we get
     1 plus 1 equals r squared cos space squared space theta space plus space r squared space sin to the power of space 2 end exponent space theta
Now putting the value of  r in equations (1)
Now the value of theta such that  and satisfying both above equations is given by
Which is the required polar form.
