I have this question that says: Find two vectors of norm 1 that are orthagonal to the three vectors u = (2, 1, -4, 0), v = (-1, -1, 2, 2), and w = (3, 2, 5, 4). I've tried setting up a system of equations to solve. 2a + b - 4c = 0 -a - b + 2c + 2d = 0 3a + 2b + 4c + 4d = 0 But when I...

I don't know if I'm just having a slow day or what is going on but I am being stumped by this: If ||v|| = 2 and ||w|| = 3 what are the largest and smallest values possible for ||v - w||. Give a geometric explanation. Would it be as simple as just adding the two values for the largest, and...

I've taken about 3 year break from this style of math, I've been doing Calculus since then. I am taking a beginning linear algebra course and I have a system I have to solve with Gaussian Elimination. I know how to work towards a solution and what Gaussian Elimination is. However when I look...

I'm working on a question as stated above for my computer science course. Since the topic was taken the Fibonacci numbers have puzzled me with their laws for simplification etc... Here is the question: http://img404.imageshack.us/img404/7668/fib0au.png I'm not sure where to start with...

Also do you guys think that when it says "the wire" is it reffering to the bottom part? The top part? or the whole thing?

If forces are in equilibrium then, the sum of all forces must equal 0. Also would I need to deal with the business of summing torques seeing as they are in equilibrium. If I did where would I get lever arm values?

A 1220N uniform beam is attached to a vertical wall at one end and is supported by a cable at the other end. A 1960N crate hangs from the far end of the beam. Using the data shown in the drawing, find (A) the magnitude of the tension in the wire and (B) the magnitude of the horizontal and...
