btw all the large As and Bs should actually be small and the a ---> det(a) should actually be large; A----> det(A). Any help is valued thnx.

there's another part to the question. analysis really is the hardest module. the uni blackboard is really quite a mess of 100s pages just for this module, i just need any help to get me in the right direction thanks :) - December 2nd 2011, 04:14 PMPlatoRe: Long Continuous proof
Why are you wrapping every thing is [tex] [/tex] ?

**Only put your equations in tex tags, not plain text.** - December 2nd 2011, 04:56 PMmaxgunn555Re: Long Continuous proof
for me i think it'll be quicker eventually. why does it not read well? any advice for the question though?

yeah you're right, you can't have letters written like they're maths letters its look weird and is quicker not to.

no help though?

the point is, det is a function from . you should already know that s(x,y) = x+y is continuous from , and that p(x,y) = xy is continuous from .

so det(a,b,c,d) = s(p(a,d),-p(b,c)), which is a composition of continuous maps, yes?
