I am just having trouble with percentages.
Lets say a town has a population of
1,000,000 in 2006
1,200,000 in 2007
1,800,000 in 2008
The percentage increase from
2006-2007 is 20%
2007-2008 is 50%
So, what I want to work out is the AVERAGE percentage per year.
The increase...

Hello. I need help with orthogonality of the fourier series coefficients. I know you can use the dirac delta function, (or the kronecker function) in the orthogonality relationship. I want to try and see the derivation using complex form rather than sines and cosines...
thanks for the reply!!!
do you mean just straight forward integrate it w,r,t, x
for example it would be
\frac{x^4 - 2x^2}{4y} ??
then what would i do with that though??
thanks so much for your help

i found a site on the internet which shows me...
brilliant thank you.
how do i show that these elements that i have generated are the actual elements though? or is it enough just to say they are?
and the fact that I havent got the same result twice from 0 to 7 means that it is primitive?
thanks so much

Hi, I need to show that \alpha+1=[x] is a primitive element of GF(9)= \mathbb{Z}_3[x]/<x^{2}+x+2>
I have already worked out that the function in the < > is irreducible but I do not know where to go from this.
