Isn't it possible to have cubic factors as well?
Do you have the question?
This is the question i have:
Let F = {0,1} denote the field of integers mod 2.
Show that the polynomial x^3+x+1 is irreducible over F.
Hence construct a field with eight elements. (You should write down the addition
and multiplication tables of your field.)
Could someone help me on this?
Find all solutions of the equation x^2 = 2 (a) in Z17; (b) in Z19.
Any ideas?
Good point, but that is the question i have a fair idea of what to do with integers but i was stumped when i read this... so any idea?
The question I have is this:
In Z13, calculate 2/3+3/5.
*Z being the symbol for integer and 13 is the subscript to it
Thanks in advance!!!
thanks people for the help!
Could someone quickly explain what converge and diverge are please?
Thanks
Don't worry people figured it out!
(a) and (d)
Am i right?
How do i integrate the following differential equation using the condition y(0) = 1?
y'= (y^2 + 1)/y
Thanks appreciate it!
Ricky could you explain to me how I get those complex roots please?
i assumed you would use complex numbers...am i right?
Hey could someone help me in this question?
Factorise the polynomial x^4 + 4 into two quadratics with real coefficients.
I have the answer from a Maths software package but i'm not too sure how the answer has come about.
(x^2-2*x+2)*(x^2+2*x+2)
I really need some help in figuring out what type of distribution the following are
i)The number of games played by a football team up to and including its first win,
assuming that there is a probability 1/3 that it wins each game independent of results
in other games.
ii) The number of sixes occurring when 7 standard fair dice are rolled.
iii) The number of marks you score on a single question on an Essential Mathematical
Skills exam which you do not know the answer to.
iv) The total number of marks you score on an Essential Mathematical Skills exam if
you do not know the answer to any of the questions.
Plus, how would i work out the E(x) and Var(x)?
Thanks!!
