Hey /sci/,
>In Calc 3 @ CU Boulder
>Need help on vector problem
>In three dimensions, consider the vector V = a1 i + a2 j + a3 k. Determine the projections of V onto
the x, y and z axis.
>I keep getting that proj of V in the direction of x,y,z are (a1,a2,a3) respectively. Am I doing well on this one?

>>	Anonymous Thu Jan 20 16:28:27 2011 No.2382688 Yes, you're right. It's a pretty stupid question though, where'd you get it from?

>>	Anonymous Thu Jan 20 16:33:27 2011 No.2382704 its from our "additional set" of hw that we have to do every week. I didn't think it would be that easy. It also asks to interpret the results. I can't really think of a way of doing that without simply showing my work on the projections...
