yasmeena Posted August 30, 2008 Author Report Share Posted August 30, 2008 For instance, in question 2, we were aked to consider the integer powers of X and Y in order to find expressions for X^n, Y^n, and (X+Y)^n . How do we find n ? Do we have to look at the pattern of answers of X and Y in the first question and get n from there (as in the common ratio is 2 so n is 2)?

blindpet Posted August 30, 2008 Report Share Posted August 30, 2008 yasmeena, use Microsoft Math, plug in the numbers and observe patterns (this will help you find n) Reply Link to post Share on other sites More sharing options...
youcantstopthebeat Posted August 30, 2008 Report Share Posted August 30, 2008 I'm not sure if i understood your question correctly, but i hope this helps:when it says consider integer powers of X and Y and find expressions for X^n, Y^n and (X+Y)^n, it is not asking you to find n, it is asking you to find expressions, i.e. where n can be any value, whether it be 2, 3, 4 etc Reply Link to post Share on other sites More sharing options...
IHateIB Posted September 7, 2008 Report Share Posted September 7, 2008 I'm doing the same project and I'm wondering if anyone has their old paper they can send me. I want to see an example of what to do because this paper is so confusing! Any advice would be helpful. Reply Link to post Share on other sites More sharing options...
blindpet Posted September 7, 2008 Report Share Posted September 7, 2008 I think this is the first year the matrix binomials came out so no samples are available yet.btw, do not forget to test for negative values of n to find all the limits you can.

youcantstopthebeat Posted September 8, 2008 Report Share Posted September 8, 2008 It will be easier to write and explain your paper if you work it out yourself. I did the same investigation, maybe i can help you. What are you stuck with? Reply Link to post Share on other sites More sharing options...
IHateIB Posted September 8, 2008 Report Share Posted September 8, 2008 It will be easier to write and explain your paper if you work it out yourself. I did the same investigation, maybe i can help you. What are you stuck with?Well, I'm having trouble finding the general statement. Are there multiple general statements that I can choose from?

youcantstopthebeat Posted September 9, 2008 Report Share Posted September 9, 2008 Well there aren't exactly a few different general statements, otherwise it wouldn't really be a mathematical general statement, if you know what i mean.As far as I know there is only one general statementTry replacing the unknowns with different values and find patterns in the resulting matrices.How to the values in the matrices relate to the values of a and b? What common factors can you find? Reply Link to post Share on other sites More sharing options...
IHateIB Posted September 11, 2008 Report Share Posted September 11, 2008 Thanks for your help! I just turned it in. Hope I did well x] Reply Link to post Share on other sites More sharing options...
jez6027 Posted October 11, 2008 Report Share Posted October 11, 2008 Thanks for your help! I just turned it in. Hope I did well x]even i am doing the same portfolio and i dont get the part about limitation and scope of the general statement....what did you write for that??Thanks Reply Link to post Share on other sites More sharing options...
Gwib Posted October 12, 2008 Report Share Posted October 12, 2008 work out different values for a, b and n.use wierd numbers, such as 1/9, 0.7 or pi. See if the formula still works for those. Reply Link to post Share on other sites More sharing options...
emir purbo Posted October 14, 2008 Report Share Posted October 14, 2008 I'm doing the same project and I'm wondering if anyone has their old paper they can send me.

sa_92 Posted October 15, 2008 Report Share Posted October 15, 2008 hey i'm doing the same matrix binomial portfolio that you are doing and I'm Lost. Can you please help me ? i dont get the part where it says "BY considering integer powers of X and Y, find expressions for x^n, y^n, (X+Y)^n. Please help me.

nabeela Posted October 21, 2008 Report Share Posted October 21, 2008 i was wondering if any one could help me out with the same thing... i understand how to get the general term bt how to i write it out..lets say for example it 3^n+1...so do i just write that...or do i include the X^n or even the matrix X beside it...??

Jernej Posted October 26, 2008 Report Share Posted October 26, 2008 What exactly are you required to do?You can express 3n+1 as (n+1)log(3) or 3n+3. Reply Link to post Share on other sites More sharing options...
Dcool Posted November 1, 2008 Report Share Posted November 1, 2008 (edited) hey i'm doing the Matrix Binomial portfolio tooyou got to write the expression in terms of the matrix value they have given youlet's say they have given you matrix value of X = (1,1,1,1) - in matrix form of courseand you find the expression for the question to be 3^n+1 (1,1,1,1)then you write in terms of Xe.g. 3^n+1 Xhope i'm clear enoughGood luck Edited October 27, 2010 by Mahuta ♥ Please do not use text speak on the forum- Maha :) Reply Link to post Share on other sites More sharing options...
