Find the projection onto the line through point a = [1 2 3] (3 x 1 vector)

a. find the projection matrix

b. project the vectors b1 = [1 1 1] and b2 = [1 1 -1]

c. find the errors e1 = b1 - p1 and e2 = b2 - p2

Please explain the answer. Basically I understand projecting one vector onto another but what does it mean to find the projection onto the vector? What am I projecting?

My other computer doesn't have wireless but this one does so I connected the two through the use of an ethernet cable. I went to my wireless connection and checked the boxes that said allow other computers to connect through this internet connection. Both computers use Windows XP by the way. On the other computer there are two connections. A 1394 connection which it says is connected but it says 0 sent and 0 received and I can't open a webpage. The other is a LAN connection which isn't connected. I'm not sure which is supposed to be working. How do I make it work?

So I want to make a desktop with a total budget of $1000 dollars. Can someone recommend me the most current, but not the best, components for the following things that you've experienced or heard good things about?

Computer Cases

Motherboards

Processors

Hard Drives

IDE and Floppy Drive Cables

SATA and SCSI Cables

Power and Panel Cables and Connectors

Memory

Video Cards

Sound Cards

Network Cards and Modems

Okay, so the problem is:

A car with a mass of 1850 kg is moving through a banked curve with a radius of 122 m. The angle between the roadbed and horizontal is 28° while the coefficient of static friction between the roadbed and the car's tires is .33.

Determine A: The maximum and minimum speeds at which the car can negotiate the curve without losing control

B: With what speed the car should negotiate the curve if there were no friction at all
