comment SimRank Example?
You obviously have a large trouble with actually reading what helpful people try to tell you. I wrote "when the value stops changing".

You need to first calculate all $s_1(a,b)$, then go and calculate $s_2(a,b)$. This is much easier to do if you have some programming skills.
13h
comment SimRank Example?
Yes, of course.

comment SimRank Example?
Right now. You can now calculate $s_1(5,1)$, right? And then repeat to calculate $s_2$, $s_3,\dots$, and when the value stops changing, you have your solution!

Also, you forgot to multiply by $\frac{C}{|I(a)||I(b)|}$

And, what are $s_0(5,1)$, $s_0(5,5), s_0(5,3)$ and $s_0(5,4)$?
13h
comment SimRank Example?
Precisely! Now, what is the formula for $s_1(5,4)$?
13h
comment SimRank Example?
Well, let's go step by step. Did you calculate $s_0(5,4)$ yet?

The wikipedia link says that you calculate $s_k(a,b)$, first for $k=0$, then for $k=1$ and so on.

Also, please read the wikipedia link. You obviously did not read the link, and if you want me to help, you need to actually do the things that I advise you. Otherwise, you are wasting our time

Do you know what "iterative" means?
14h
comment SimRank Example?
Yes, it's correct. But since you said you know the link, do you know that you need to calculate the rank iteratively?

What do you mean you don't know how? At which step are you stuck? It's very hard to help you if you don't explain what you tried and where you got stuck...
14h
comment SimRank Example?
But did you try to calculate the value yourself? I mean, the wikipedia link pretty much explains everything you need to do, so I don't know what else you need...

comment $\sin(x^2)$ in terms of $\sin(x)$ and $\cos(x)$
@AlanGIC Why would it embarras you? You did most of the work, since you were the one who had the idea of using periodicity. I just helped you clarify your thoughts :)
