Thanks again that totally clears it up for me.
I have another question for you:) I recently lost a month of studying because of medical issues... The only part of Linear algebra I haven't covered is the chapter dealing with eiggen values (not sure if I spelled that correctly) I see that some complex number skills are required for that chapter and i've never done complex numbers before. I went through the past 3 years exam papers of my university and it seems like eigen vallues rarely appears and if it does it counts maybe 7/100 marks. i'm writing Linear algebra on 23/10 so not much time left. So right now i'm not sure at all whether just to forget about the eigen values and focus on the other work or try to learn some basic complex number theory and do the eigen value chapter as I have 4 other subjects this semester... What would you recommend I do? would it be possible to learn enough about complex numbers to use in a elementary linear algebra course?
Good to know you're still on these forums, I remember you helped me get past a lot of challenging problems last year.
I think so, is this the way to do this? Sorry for the bad notation i'll have to go over the LaTeX post again...
Thanks a lot
Hi all I recently started linear algebra and my prescribed book seems to require some 3-dimensional geometry knowledge which i've never touched... Any idea how to go about this?
Let L be the line that passes through the points P(2,4,-1) and Q(5,0,7) Determine the point of intersection of L and the x-y plane
Should the z-coordinate be 0 because the question only mentions the x-y plane?
Hi all I have no idea how to start this equation the exponential equations I have done so far were all more or less the same (becomming a quadratic equation which made it very easy to solve X)
Hi all. Am I doing this correctly?
In a factory 2 different machines A and B are used to fill bottles When the machines work together they fill the bottles in 2 hours. Machine A works twice as fast as machine B, how long does it take machine B to fill the bottles when it works alone? What i've done:
