ahhh ok i understand - see i didnt even understand the theory behind it! i get it now - thanks! :)

I'm sorry I am not really understanding? I derived the expansion and then I didn't know what to do after that?

Hello - I have a problem in general finding the region in which the Laurent series converges... Could someone please help me with this question - I know that this is is meant to be easy (as there is no fully worked solution to this) but I don't understand it: f(z) = 1/ [(z^3)*cosz]...

thanks!

Homework Statement Hi - i have fully worked solutions in my notes, but i do not understand this step in the proof. Proposition 3.16. Suppose that W is a subspace of a nite-dimensional inner-product space V and let v be an alement of V . Then ||v - projW(v)|| <= ||v - w|| for all w is an...

thank you!

Thanks for you reply. I intended to have lots of equations like: a = b = c = d f = g = h = i and like for them all to be aligned at the equals signs. Is that possible?

Homework Statement Hi, I was just wondering how to write a = b = c = d all aligned - like not in 2 columns I have been messing around with & a lot and I still can't get it. I know its simple I just am a first time user of Latex so any help would be aprreciated!

Hey Gabby - thank you for pointing that out (i can't believe i didnt see that!). I will try it again now - maybe I have done some stupid mistake.

Homework Statement I am trying to prove an identity and in order to finish the proof i need to show that: for z a p-dimensional vector and A a non-singular square (pXp) matrix - also note that T is transpose - : zTA^(-1)z = zzTA^(-1), where -1 denotes the inverse I have looked...

thank you!

Hi I am trying to do a math assignment and I am finding it really difficult. Assume you have a linear transformation from T: P3(R) --> R4 What relevance is there to applying the transformation to the basis elements of P3(R), ie: T(1), T(x), T(x^2), T(x^3)? Why is this subset special...
