```										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
