Hi Im looking for discrete mathematics and algebra books to study. I want to enhance my understanding of algorithms and programming and i like discrete mathematics I'm reading Apostol for this semester's calculus (took a look at spivak too). Any book as good as them that will be useful for me ?

What i actually need is way to deal with the fact that i can't work with great numbers in C i don't know what the problem is The Leibniz's series i said up there , is a summation . I couldn't calculate it because double variable types had limited digits ... i tried multiplying by 10^n and...

Sorry still confused .. can you write algorithm ?

How is that formula can calculate Nth digit of Pi i don't get it

First that typing faster means you had more experience coding (and you wrote a bigger variety of programs) but this one is way beyond slow Second that I'm first semester i don't know any other teachers and they won't answer unless they know me

This is university ... The teacher (or should i call university teachers professor ?) got his degree from the best university in Iran .. it shows that he doesn't have much experience ... Just ask him intermediate questions and he can't answer more than half of them I asked fifth semester...

No , the teacher connected his laptop to projector while he was teaching C his typing speed wasn't much different of a beginner ... I think he was two-finger typing Still seems implausible ? FYI I am from iran.

Hi I was thinking about calculating Pi digits (for example up to 1000) using C programming Unfortunately there seems to be no one in our university to know how (even teachers) I know that i have to use arrays but i don't know how And i don't know what is the best way to do it ? -4 times the...

Hi I recently upgraded to windows 8.1 from widows 7 I have a program which connects to a VPN server . Since upgrading to windows 8.1 it doesn't connect any more it gives ssl error The time is correct and i have tried turning firewall off but it doesn't seem to work The server I'm connecting to...

The next session he came and said that he will give us points if we solve this. I don't think he himself has solved it .. I think i should prove that theta would be variable no matter what starting theta we have to show that problem asks for a wrong thing

That it will change forever

So your saying that if initial angle was 0 it will going to change until m1 hits the ground ? wouldn't it become constant after some time passed ? And can you prove it ?

There is no text he just drew it .. no drawing of initial position and accelerations are not required I found a way ... got sin(theta) = m2 / (2*m2+1) i don't know if currect or not (it seems odd that its only depended on m2)

I think theta here is depended on m1 , m2 and m3 ... it is solvable , but not the way the teacher taught us to the problems were very simple compared to this

I think theta is for when the base is moving not while we haven't released m2 And no friction between m2 and m3
