Given a function of f(n) = nCr, where r is a constant,
example like, r=3, then f(6) = 6C3

How to get the differentiate of the function, ie f'(n)?

I think because nCr = n!/[(n-r)!r!],
and n! is differentiable by using gamma function, differentiate nCr is possible. But I can't even confirm whether I do it right on differentiate on n!, I got stuck on differentiate nCr.

Anybody could help me on this?

I admit, I really blow at math. Please help me out and work these problems out for me. Pretty please? Thanks.

Given that jmx=1/dq, solve for d

Given that 1=q/asuz, solve for s

Given that 1/y=1/bhjz. solve for j.


solve for x

13/9=4/3x + 9/27

13/28 = 6/4x + 20/16

6/x = 84/48 - 46/36

23/42 = 41/24 + 13/5x

13/24 = 54/32 + 6/2x

Hi all. I am an Iranian Moslem. I just wonder is there an end for the space? And if so what do you think is beyond? Some scientists believe that space is growing all the time. Some believe the size of space never changes. Some believe space is unlimited. But I think it has to be limited. Imaginary I think if we keep traveling in the space in a direct path we will finally reach the point from where we have started our long journey! But that doesn’t mean that I think space is unlimited. Maybe that would be because of black holes or some other unknown forces. I think if we could pass the imaginary borders of space we would find ourselves in another space different from our own black space! Remember Matrix? I think worlds are inside worlds no matter how big they are and creation of other worlds would continue forever because God wouldn’t stop creating new worlds and new creatures, would he?
Are there any aliens? Why do you think God has created a space that is so big? Maybe to prove us that he is so powerful. But isn’t our own Earth wonderful and big enough for us to believe in God? So I think there has to be creatures other than us in other galaxies but not necessarily as clever as us. What do you think?
Recent analyses of Koran show that the words: day, month, imam and world has been mentioned in Koran in this manner: 365 times, 12 times, 12 times and 115 times! You see that the number of repetition of the first three words is not by accident. Because there are 365 days and 12 months in a year and we do have 12 imams! So does it mean that there are 115 worlds? What do you think?

universe consists of Stars, Planets, comets, asteroids etc.,. It is called universe? Then, is there other universe outside the universe? I mean, universe is just like the shape of Earth and once it was believed there was only star, moon and sun, later that concept was changed. Also people thought Earth was flat and that concept was also changed.

So is the universe is shaped like a Globe, semi-circle or an ellispse?
