    Complex Analysis: Finding Arg(z)

    Thank you so much Hurkyl... your help is much appreciated! In the meantime, I also found http://scholar.hw.ac.uk/site/maths/topic11.asp?outline=no" page, which led me to believe that I was right. Your reply, however, gave a positive confirmation of my guess. Thanks again - now I have a much...

    Complex Analysis: Finding Arg(z)

    I found this on Google: The argument of a complex number is the angle between the positive x-axis and the line representing the complex number on an Argand diagram. It is denoted arg (z) So Arg(z) is pretty much just the angle theta that r makes with the x-axis? Assuming that arg(z) is not...

    Complex Analysis: Finding Arg(z)

    This Arg(z) thing is new to me, so no. I'm trying to find out what it is. Thanks.

    Complex Analysis: Finding Arg(z)

    Hello everyone, I am trying to solve this follow problem, but don't quite know how to go about getting Arg(z). z = 6 / (1 + 4i) I got that lzl is sqrt((6/17)^2+(-24/17)^2) but am stuck with finding Arg(z). It told me to recall that -pi < Arg(z) <= pi Can you guys teach me how to go...

    What is the moment of inertia for a square rod using the parallel axis theorem?

    Hi all, I have run into a problem requiring the use of the parallel axis theorem. I'm kind of lost as to where to start. Can anyone help? A thin, uniform rod is bent into a square of side length a. If the total mass is M, find the moment of inertia about an axis through the center and...
