Dear nilandri sarkar


principle value of an argumnet is a perticular value of argumnet that lies between  


 -pi< prinipal argu <= +pi


 for example


 let a complex number  z=1+i


                                    =√2(cos pi/4 +i sin pi/4)


                                     = √2(cos (2npi+pi/4) +i sin (2n pi pi/4))   here n is intiger


             here argument can be any value  for differen value of n


             but principle argument value  is pi/4      lies -pi< prinipal argu <= +pi
