The equation, solved, wound up being a = 127/23, b = 170/23 if I recall correctly. I made a couple very basic mathematical errors which turned this simple problem into something that I thought warranted a thread. But, again, thanks for the help. I'm at least pleased that my initial plan of...

Yeah I just suck at basic arithmetic. Thanks a lot for the help, this shouldn't have been anything like as difficult as it was!

I'm not sure what constitutes (i+1) in this problem. Which equation is that?

Would anyone be able to help me out with this? I hate to be a pest, but it's the last question to a homework assignment and I've been struggling with it since yesterday. The assignment is due at noon EST today (Friday) and I'd really like to figure out an answer before that deadline.

Yes, I messed up my signs there. The problem I'm faced with, now that my own stupid mistake is out of the way, is how I do something with the two separate values of a which I get for both proving the i-hat and j-hat statements true. In the case of the i-hats, a=(8b-26)/6 whereas with the...

Homework Statement If Avec = (6.00 ihat -8.00 jhat) units, Bvec = (-8.00 ihat + 3.00 jhat) units, and Cvec = (26.0 ihat + 22.0 jhat) units, determine a and b such that a Avec + b Bvec + Cvec= 0. a= b= Homework Equations Avec + Bvec = Rvec Rvec = (Ax + Bx)i-hat + (Ay + By)j-hatThe Attempt at a...
