I'm wondering about something similar. I plotted some points in the transformation and it seems to be a circle but I can't manipulate it to get it in a form where I could find the radius or center.

Oh! I see now, thank you.

Homework Statement [/b] Graph the locus represented by the following. \left|z+2i\right| + \left|z-2i\right| = 6 Homework Equations The Attempt at a Solution z = x + iy so z-2i = x + (y-2)i and z+2i = x + (y-2)i So I have: sqrt(x^2 + (y-2)^2) + sqrt(x^2 + (y+2)^2) = 6...

Yes, the symmetry group. I'm not sure I entirely know what you mean with Lagrange's theorem. I'm not sure how that exactly helps. And breaking up each permutation into transpositions, won't that just make the brute force easier?

How would one go about proving a particular subset of S4 is a normal subgroup of S4? Since S4 has 24 elements, I'm wondering if there is any other way to prove this other than a brute force method.

Okay, I was able to get on there and now I'm looking into this MAC filtering. So I should probably enable MAC filtering (only letting those people I allow to connect) and disable SSID broadcast?

Sorry for the long response time but this the first time I've been able to access this computer in weeks. Sure. I have a Linksys router model WRT54G. I looked on Linksys website for setting up a password but I couldn't find anything. I saw how to change the router password but I don't...

I'm looking for all the computer experts out there. I have a wireless network in my house; I have one desktop computer that is directly connected to the modem (I have a cable connection) and another desktop computer that receives the internet signals via a router. I also have a laptop that I...

So you've chosen the tabletop as your zero reference point?

That looks correct but I'm just wondering what you're motivation was for integrating the potential energy?

That's going to involve solving a second order linear ODE. I was thinking that you can go through this problem with only separation of variables.

Homework Statement A flexible rope of length 1.0 m slides from a frictionless table top. The rope is initially released from rest with 30 cm hanging over the edge of the table. Find the time at which the end of the rope left on the table will reach the end of the table (basically when the...

I have no idea how we're supposed to get things like cos(\beta)

I too am having trouble with this problem. In the book, they use Taylor expansions in order to find the flight time T and put in back into the range equation. However, they have the luxury of letting y = 0 because the trajectory is a simple parabola. We don't have the same situation here. y...
