hey folks, it is the no.of solutions for the equation x+y+z=n(here n=10) ,x>0,y>0,z>0 so the no of solutions is n+r-1C(r-1) where r=no.of variables(i.e 3 in this case)..so 10+3-1C3-1 =12C2=66cheers!rate me if u like it!

^for x=0,1,2 lhs is less than rhs but for x=3.. lhs is greater than rhs

*for x=0,1,2 lhs is rhs

if x=0,1,2,the l.h.s is rhs so the value of x should be in(2,3) so let x=2+y where 0<=y<1..so we get (2+y)^2=4+2=6 solve it dude.. :Drate me if u like it

2^0=1=1 digit2^1=2=1 di2^2=4=1 di2^3=8=1 di2^4=16= 2 di2^5=32=2 di..2^7=3 di..2^10=4 di...if u observe carefully there is a pattern here...the increment in the number of digits starts from 4,7,10,... which is a sequence in A.P so the nth term is 4+(n-1)3=3n+1..so for 2^22,22=3n+1-->n=7 for n=1,no.of di=2,for n=2,no of di=3..so for n=7,no.of di=8.so no.of digits in 2^22=8..for 2^2^22,2^22=1024*1024*4=3n+1-->n=1398101..so no.of digits in 2^2^22=1398101+1=1398102.. :Dcheers!rate me if u like it :)

hence by sinmply putting a=3 ,the above expression will be zero..so a-3 is one factor and using division we'll get a^2+3a+2 as another factor whose factors are a+1 and a+2 so the factors of above expression are a+1,a+2,a-3 cheers!

in F.C.C type of  ionic crystal

whether 2r++2r-=a or 2r++2r-=a?

how can we know whether it is an integrable or non integrable function?

hey
you should remember that,all expressions should have a least value when all numbers are equal
hence,
=1/2absinc     put a=b=c=p=q=r
then  delta=1/2a2sin60=[2 ] 3/4a2 .therefore,a2=4delta/[2 ] 3
then the given expression leads to
a3/2a+a3/2a+a3/2a=3/2a2
=3/2.4/[2 ] 3.delta
=2[3 ] 3.delta
hence proved

anmswer for 2nd Q is 2
try by taking logarithms
cheers

no
the numerator is 1+8x3 and denominator is x(1-x3)
similar for y also

hey,
cosx.cos(a-x).cos(a+x)=1/4 cos3x where a=60,120,240,300
hence cos20.cos(60-20).cos(60+20).cos60=
1/4cos260=1/16
