hii,pushkar can u just nudge me and tell the type of problems that came up in bits as my exam is on 7th june .and by the way even if ur net total is not 80 in cbse you may ask the pilani authorities (helpline numbers in brochure ) if they may provide you admission after scoring a brilliant knock of 350+

log (x!)= sigma{n=1 to x }log n

using computation complexity of sorting algorithm(comparison sort)

we get the estimate as

xlog(x/e) +1<= log x!<=(x+1)log((x+1)/e)+1------1

our great scientist ramanujam gave the series as

log(x!)=xlogx  - x +  log(x(1+4x(1+2x)))/6  +  log pi/2------2

I cant give the proof of 2 as I am not ramanujam however if you want to know more about 1 I will tell u some day      :P

I dont about u guys ,but in the centre where I have given the paper the OMR sheet was having the questions in order of chemistry,physics and maths while in question paper the order was chemistry maths and then physics , utter carelessness!

This Post 9 points    (Olaaa!! Perrrfect answer.   in 3 votes )   [?]
the answer is very simple(perhaps if im correct lol), as u know that any fluid has a surface tension and that it tends to align itself in smallest surface area , (circular for water droplets), hence when mosquito is dipped the water droplets stick to its wings and folds its wings in circular shape, which makes him difficult to fly.

Catalogs Discussion Forums -> Algebra -> In a right angled triangle the hypotenuse is 2,/2(two root two) times the perpendicular drawn from o -> Go to message
This Post 5 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]

this is very easy.consider a triangle ABC right angeld at B , let we draw a perpendicular from B meeing AC at D. let length of BD be " p"units,

then AB =p/cos (theta)  and BC = p/sin(theta) where theta is angle BCA.

now AB2 +BC2 =AC2

     so (p/cos(theta))2+(p/sin(theta)2=(2sqrt2p)2

        or sin2theta=1/sqrt2

       or theta = pi/8

   other angle = 90 same as(540/8)     loL

The weight of an empty balloon on a spring balance is W1, THe weight becomes W2when balloon is filled with air,let weight of air itself be w(neglect difference in density and thickeness) then

a)W1=W2

b)W2=W1+w

c)W2<W1+w

d)W2>W1

ans(a,c)

pls explain
