Can you please explain the differencs between argument & principal value of a complex number?
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 Please feel free to post as many doubts on our discussion forum as you can.

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
