I am reviewing a proof at the moment and there is terminology that I do not understand. What does it mean for a polynomial to have "integral coefficients"?
"Integral coefficients" means that the coefficients of your final answer will be integers, unless there is a markedly different context in which the question is being asked.
You can have a look at the definition here.

I am trying to model and plot a line of best fit through this. I though it was a quadratic, however this does not fit the data well at all.
plot(bResultsRan~effort, data=BRRan)
lines(fitted(glm(bResultsRan~effort+I(effort^2), data=BRRan)))
summary(glm(bResultsRan~effort+I(effort^2)+I(effort^3)+I(effort^4), data=BRRan))
This is my output at the moment, I hope you can see why it does not look to be a good fit? Do I need a higher order polynomial?

I tried using recursive tree method.
and got a geometric series.
That follows :
kn^2(1+ (3/2) +(3/2)^2 +...+(3/2)^b)
The sum = a(r^m -1)/r-1.
b = log n.
Then what to do I got confused.
Have you heard of the Master's Theorem? Your example is a relatively simple subcase (no logarithms). The result is:
T = Theta(n^2)

What are the accurate mathematical or scientific symbols to represent MIN and MAX? Thank you
you can use something like this:
max(f(x))=k

There's a new language Q, based on R, which was based on S ... you get the idea.
Sadly, Q appears to be very slow in automining unicoins. Plus, Q : we don't have TIME for your little games!
Clearly Q is backwards compatible to R so it inherits its speed. This is by design. Happy mining!

I have found this formula for computing Pi value:
But I need to compute only(for example - 1000th) number of Pi value. How I can do it with provided formula?
Thanks.
What you want is called a "spigot algorithm". Take a look at [1] in the section "BBP digit-extraction algorithm for pi". Good luck and have fun.
