I do not know that there is an 'offline' version.  There might be I'm not sure.

what is 0.0476190476190476 correct to 4 decimal places

Look though this  

Type it into the web2 calc as 

acos(60/76)=

that will give you the answer

arc cos is the same as inverse cos

Chris is right but to me the question uses confusing words unnecessarily.

There is only one way that x can approach infinity.  

I am probably wrong but I think the wording is silly.

Think about this.

the question is actually asking How many 0.09s are there in 3.6

Well there are a great many, because 0.09 is a very little number.

10 lots of 0.09 are 10*0.09=0.9        3.6 is a lot bigger than that!

20 lots of 0.09 are 1.8                        3.6 is still bigger

infact

0.09 added to itself 40 times = 3.6

0.09*40=3.6

so that is why

3.6 divided by 0.09 = 40              

Mmm lots of good numbers it seems.  All good reasons too.

I've always been partial to 17 though my logic is a lot more obscure than Rosala's.

!7 is is prime, it is 1/3 of 51 which also gives me fuzzy feelings for no particular reason.

Now i know it is Rosala's birthday that makes it even better!

Phi has been mentioned a couple of times in the last week.  I didn't know it befor that.  It really is a COOL number.  But, it would but difficult to encorporate into a locker locker number or to use on a lotto drawer.  LOL.

16 is a very COOL number too.  It is my birthday.    

143 is very obviously a great number.  I do not need to say more on that, although 243 is pretty cool too because it is 3^5.

So  (3^5- I love you)/100= 1      How about that!

Well I have it on my Samsung phone so yes!

Thank you, I am glad I helped you.

Well, you are multiplying by the lowest common denominator.  

What does the question say?

Well your friends are missing out.     Silly them!
