I'm really sorry but I still don't see how to show that B*0v = 0v --where B is a constant. Are you suggesting that I add the vector u to each side of the eqn?

Thanks for answering the first question, but any ideas about the second (aX = 0)? These vector spaces really have me confused.

Hi, I'm having trouble with these homework questions. I have to prove that B*0v = 0v , where B is a scalar. Also, I have to prove that if aX = 0v , then either a = 0 or X = 0 ---where a is a scalar and X is a vector. I know that I have to use the 8 axioms but I'm not sure...

I'm in a intro to circuits class for non-EE majors. One of the homework problems asks for the equivalent resistance. See the attached file for a picture of this system. I know the first step is to add resistors R4 and R5 (in series) as well as add resistors R6 and R7 (in series). But...

Mechanics of Materials Bending Stress Problem Hi, I have a homework problem for mechanics of materials involving bending stress. Here is the exact wording: "Show that the maxiumum bending stress for a beam of rectangular cross-section is Omax = Mc/I [(2n + 1) / (3n)] if instead of...
