Most difficult 4u q? (1 Viewer)

It is related to the determinant of a 2 x 2 matrix with entries [a b/2 b/2 c], although some fiddling obviously occurs to get the easier form...

Isn't it called the discriminant?

Well yeh i figured that, but i've got papers from 90-00, and that was the hardest polynomial q.

I think you do the matrix form derivation of determinant in first year (eigenvalues and eigenvectors) btw... or is my memory of the courses just blending together?

Sort of, a lot of it is done realy quick (Volumes in one lesson!), but that just means that you are disadvantaged if you havn't already done it ...

no but i'm just shocked at the rate....i mean what about once we reach topics that we haven't done in 4u...then i'll b stuffed, coz they'll only spend one lesson on it.

You can just ask someone next to you, which is probably a great way to make new friends in uni too

its not that, but the work load is huge and its prolly not gonna decrease by asking someone next to u....it might even waste your time.

Everyone else is in the same boat.

hahaha i think my maths class spent only 2 or 3 morning lessons on it cuz we were so far behind.... we did the harder 3 unit topic in 1 lesson... hmmm

Our teacher told us to do it ourselves, so no lesson's on harder 3u.

But doing harder 3u is pretty much studying for 3u right?

yeah, same here...my teacher just said look over your 3u notes.

well we went through harder inequalities and inductions where you assume all cases before k+1...

what the hell, never even heard of such a thing.

 

[underthesun]

I think he meant "strong induction", (Bill Pender's term), for example fibonacci sequence, that for k+1 to be true, k-1 and k has to be true.

omg whats that?

cambridge have it?
