Title: Re: A request
Post by: astarmathsandphysics on May 25, 2009, 03:29:28 pm
(a+b)n=nC0anb0+nC1an-1b1+
nC2an-2b2+......+nCna0bn

I cannot understand it. Im trying since days.
Title: Re: A request
Post by: amdoo on May 25, 2009, 03:43:54 pm
binomial means two names the first name identifies the genus of the organism and the second name identifies the species

LOLLLL!!!! i get it!!! astarmathsandphysics was talkin abt the binomial theorem for maths!! n samin6n was talkin abt the bionomial systms in biology!!!!
 :D
Title: Re: A request
Post by: melony on May 25, 2009, 04:15:45 pm
By the way samin6n:
binomial classification is the sytem of naming living organisms (and extinct 1z) using 2 part scientific (Latin) name. GENUS+SPECIES e.g Homo Sapiens

Is there a binomial system in biology?
Title: Re: A request
Post by: sweetsh on May 25, 2009, 04:18:01 pm
Hahahahahahaha yes! But thats totally different thing.

There are 2 more. I only gave the one for n a positive integer.

yaa..there is a binomial theorm in math too

here in india..its hardcore math for the cbse..
i turned to igcse after my grade 7..
but well!!...add. math covers much of the portion

(a+b)^n = a^n + nC1 a ^n-1 b + nC2a^n-2 b^2 +.............b^n
Title: Re: A request
Post by: Ghost Of Highbury on May 25, 2009, 06:11:49 pm
we learn binomial theorm in additional math
permutation and combination too!!
quite tricky but easy too
Title: Re: A request
Post by: Ghost Of Highbury on May 25, 2009, 06:19:16 pm
the power is usually low in additional math for binomial theorm as in  1<= n <= 10
some of us who find combination method difficult use the triangle law
i don't remember the name for this
its like this

             1    1
          1    2     1
        1   3     3      1
     1    4   6      4     1

and so on ...keep on adding the middle numbers of the previous row..to get the next one..

for example if they say to (a+b)^4 --> the power is 4 soo chk out d pattern in the triangle
its 1 4 6 4 1
these numbers will act as coeffecients..

therefore (a+b)^4 = (a+b)4 = a4 + 4a3b  +   6a2b2   +   4ab3    +    b4
