I am offcially really confused. Okay, so I haven't done so well in math this semester. And by havn't done well, I mean that I've slept through every class, because I've already taken multivar, and I'm just generaly a bad kid, so I'm was getting B. Near the end of the semster, I didn't do the homework quite as frequently as I should have. Then

Yeah...I'm glad to hear your happy grade story, but I don't have all that many of those this semester. Actually, I have one. But I took the multivar final tonight and...if I get better than a B in Multivar, that's unexpectedly good.

The reason the slope is steepest in the direction of the gradient is that you dot the gradient with the unit vector in the direction you're traveling to get the change. When you dot a vector with itself, the angle theta between the vector and itself is 0 and thus the the cosine is 1. Using A dot B = |A||B|cos(theta), we know that the dot product (or change) is a maximum when cos(theta) is a maximum, thus when theta = 0 or the vectors have the same direction.
I wish we'd had that one.

I was definitely hoping to go to training while I'm home. I think Casey might come too. It will be very cool not to be the only alum there!

Thanks buddy! Glad you liked it!

This makes me very, very sad. My lj now has math problems in it. I think the only way that I might forgive you would be if you helped me with my parent's home networking requests. Is there an easy way to add wireless capabilities to a wired router? Like, my parents want the two desktops to still be wired, and not have to put wireless thingies in the, but they want a wireless option for my sister's and mom's laptops. Do we just get a little transmitter thing that can be plugged into our router, somehow hook it up to an additional wireless router, or do we have to get a new router that somehow has both? Sorry if this is totally incoherent, I'm not so good at explaining things.

Yes, it's easy, that's what I have here. Any wireless router will serve as a wireless access point. You just set the thing up as in access point mode and plug it into one of your wired network ports (use one of the numbered ports of the access point.) Make sure you set your security well (because I'm paranoid), use WPA PSK, silence your SSID, and I like MAC address filtering. If you have any questions, just ask. I'll be happy to talk you through it.

Also, I think that's a good math problem. I ended up getting a very high B+ on my final (almost A-) and a B+ in the class.
