Unless both a and b are 1.
Of course. I should have said that it in general doesn't hold for integers.
pibbur who stands happily corrected
Unless both a and b are 1.
This is what happens when someone divides by zero. I blame myself.Gah! Go away with your maths.
I know the rule of three …
The Integral from sin(x)/x := Si(x)
Mr. Taylor is your friend:
sin(x) = x-x^3/3!+x^5/5!-x^7/7!…
sin(x)/x = 1-x^2/3!+x^4/5!-x^6/7!…
Integral: Si(x)= x-x^3/(3*3!)+x^5/(5*5!)-x^7/(7*7!)…
The problem with this thread is that within the scope of inifinite knowledge each of us can only know a small finite amount. While no two of us probably know the exact same things and it is likely that each of us know at least one thing that no one else knows; the question is how much of what we don't know do we really want to know ?
Yepp. I was a bit evil there. sin(x)/x is a simple, nice formula, so one might be tempted to find a simple formula for the integral. Which is not possible, you have to use a Taylor series, (which you can get as close to the real function as you want, of course).
But I admit this was perhaps a bit over the top. Many watchers have no experience with integration, and if they do, they (many of them) have forgot it.
So I'll drop plans plans for entertaining aspects of differential equations, Fourier series, and above all the Fast Fourier Transform.
pibbur who has to admit that most watchers probably doesn't find mathematics as funny as he does.
Please go on with the Maths… it is a fun diversion here from time to time…

BTW: All things about Australia belongs here
Oi! (Some) Australian stuff matters to some of us!!
Why not a poll to choose?
Well, actually I have decided to stop that part of my posting.

I really doubt that anyone here felt that you were offending anyone, and certainly not intentionally.
