2nd.....cuz in the rest of the two his death is assured..but in the second Anything may happen ! (prob of his dying is 1/2)

I think CN- with Iron will be more stable simply becuz the bond order is higher.....higher the bond order the more stable a compound is....I MIGHT BE WRONG
|
|
|

Lim (1^x+2^x+......n^x)/x
is the answer by any chance
log n!

Guyz do u think someone shud make a munnabhai iit ? just imagine the plot...though most ppl wont relate to it we wud have a blast seeing that moviee ...... any comments ?

i am not a teacher expert or watever...i am an aspirant
to understand inverse trigo DONT BY HEART THE FORMULAE...UNDERSTAND HOW IT COMES !
sin -1 (x) =cos -1 (1-x2)
Understand y it is so....
sin inv x = y (say)
sin y = x
square
siny2 = x2
1 - cos y2 = x2
cosy2=1-x2
root
cosy= root 1-x2
thus cos inv root 1-x2 = y = sin x
spend a lil time reading these proofs and then later when u practice sums the thinking time will reduce
to remember derivates of inverse trigo
use mnemonics
For eg. u might know derivates of sin tan sec are positive
while that of cos cot cosec are negative
use the following sentence to avoid confusion:
SiTa Se Achi Umeed Ki Jati Hain...
si = sin
ta = tan
se = sec
achi = positive :D

and wat about iitg (or lower iits ? )
|

Good Sum....I Got 1 as the answer too here is my method :
lim [1+x] log [1+x] - 1 / x
Use Magic(Hospital Bhaiyya's Rule ;) ) ,
using u v product rule for numerator ,
(1)log [1+x] + [1+x]/[1+x]
x > 0
1+x NOT EQUAL to 0
therefore 1+x gets cut
what remains is log [1+x] + 1
1+x = 1
log 1 + 1
0 + 1
1

Guyz plz plz help me......cuz i wanna drop all iit hopes if i feel that its outta my reach (think realistic NOT POSITIVE acc to me).....if not the above question atleast temme : which requires a higher rank among the following at iitb (please estimate the rank)...
mech
mech dual
chem dual
chem
what is the rank required to get the above stream at lower iits like iitg ?
|
|
|
|
Guyz what sorta rank is required to get mech (dual or single) at iitb or any other iit ?
give separate info for dual and single if possible....i dun expect u to point out precise number...an estimation wud be highly appreciated !
Please Reply (Experts & Members)

this is what i do when i get real sleepy (i dun attend fyjc college much ) and i study mostly at nites (upto 3 sometimes) that time i am bound to get sleepy so what i do is...
I play a song real loud on my iPod which is either very high energy or a live version or has heavy riffs [ENGLISH.....I DESPISE HINDI SONGS] if u want i can give u some names of songs that u can experiment with....it worked for me

if a b c are postive NATURAL numbers the answer is 6
if a b c are ANY positive numbers the answer is no conclusion (as far as i know)

Guyz please EXPLAIN to me how to solve the type of sums :
1.where u r given a number (for eg. 12345) and u have to find the sum of all possible numbers that can be formed from it...I dun want answer i want to know how to do it...
2. 5 letters are to be kept in 5 envelopes......in how many ways can the mailer post the envelopes with NOT EVEN A SINGLE envelope addressed correctly...
Please EXPLAIN both sums if u can (or one )

I Agree with guy above me....i reached same answer...12C9

Do NITS give addmission on state rank or AIR ? cuz i heard of a guy from assam who got aie 50,000 something and sr 13 and he got into warangal....i am from maharashtra....and concerned about warangal/trichy/surathkal...do these give on sr or air ?

Dude,
First things first...r u well versed with ur 10th portion...dun be too overconfident...
2nd
which state r u from ? (if u r from maharashtra there are some things i cud tell u)
[btw i am 2008 aspirant]
3rd
get started with following books :
NCERT Of All 3 Subjects (PCM)
H C Verma (Phy)
O P Agrawal (Chem)
M L Khanna(Math)
Some ppls point of view may differ....but i found these books good....most ppl might not think of ncert books as a good way to utilise ur time but b4 tenth i wud suggest low profile stuff like ncert later when u come into the battlefield that time u can use a das gupta and others

Here Are 2 (which most of u already know i think)
1. when a matrix is given and its inverse is asked for (along with 4 options) instead of solving the matrix to find the inverse, its much easier to multiply the matrix to the 4 options... AxAInverse=1 there is no need to multiply entirely...if u get some number which is not 1 in a11 stop and goto next option or else continue
2.similarly when 3 equations are to be solved using matrices and options r given best way is to substitute values of x,y,z.....

1.Guyz i am iit 2008 aspirant....is it ok if i leave out centre of mass and rotational mechanics and come back to it later (after doing optics elec etc) or do i need the concepts later in optics/elec/wave theory etc ? (most probably not i feel but wanted to verify)....
2. Can i just leave out mechanics and come back to it later....after optics etc ?

y does 1-sin imply sin =1
u can cancel frm both sides if the term is not zero...clearly if sin will be 0 lhs will be 4 which does not give the solution....i din write that step...thanks for pointing it out though...yeah and i wrote only general form

The Answer Is Simple
Its Sin Inverse Of -7/25 (Around 16.2 Degrees)
sin = s
cos = c
4c+3s=3
c + 3/4s =3/4
c =3/4 (1-s)
Square
c2 = 9/16 (1-s) (1-s)
(1-s)(1+s) = 9/16 (1-s)(1-s)
1-s Cancels
1+s/1-s=9/16
By Componendo Dividendo
1/s = 25/-7
s = -7/25
Thus Theta Is Sin Inverse Of -7/25
Or 16.2 Degrees
