can someone tell me fast??

its urgent!!

expected 148

got 125

state TN 708

AIR 30209

i belong to TN

i got state rank 708
n AIR 30209

wat college can i expect??

can someone tell me soon?

2ax + 2by +(a^2 + b^2 -k^2) = 0

thnx pals!!..i think this requires a more practical learning!

shevchenko..buddy...i just dont know wat it is...i saw it first only in the IIT brochure wher the syllabus is given[/)]...

ramyani...hmm...ithe diagram isnt clear..

can u give both give any links wher this is clearly explained?

yeah..i want the whole thing...
i havent even heard of this b4..

Can anyone tel me how to determine the specific resistance of a wire using Post Office Box method?

It wud be more helpful if some illustrations r also given..

Can anyone tel me how to determine the specific resistance of the wire using Post Office Box method?

Can neone explain me the principle on which carbon dating calculation is done?

i mean the physical process which leads to such a calculation..

condition for concurrency, delta =0

| a 1 1 |

| 1 b 1 | = 0

| 1 1 c |

applying

(C₂ - C₁) and (C₃ - C₁)

delta = a(1-a)(c-1) - (1-a)(c-1) - (1-a)(b-1) =0

dividing by (1-a)(1-b)(1-c), we get

a/(1-a) + 1/(1-b) + 1/(1-c) =0 , v get

1/(1-b) + 1/(1-c) = 1a/(1-a)

add 1/(1-a) to both sides,

1/(1-a) + 1/(1-b) + 1/(1-c) = (1-a)/(1-a) = 1

Sir,
that waz indeed useful...yet
in the sloution..there's one more line in addition to x=2..
how do v account for that?

| 1 2 1 |

| 3 4 1 | = 1

| x y 1 |

on evaluation gives, 2x - 2y + 3 = 0

and the given condition gives x^2 + y^2 - 4x -6y +11 =0

substituting the first condition and simplyfying we get

5y^2 - 18y +4 =0

the discriminant of this expression is +ve..hence it has 2 real roots..n fer each root v hav one value of x..

hence maximum no. of such points C is "2"..

The equation of the line(s) thru the point (2,3)

and making an intercept of length 2 units between the lines

y+2x=3

and

y+2x=5 are...

A number of factors lyk the direction of the area vector,the direction of the magnetic induction and the direction of the current play a role in determining the sign of E

the right-handed rule n Lenz/s law are the most important ones for determing the direction..as full explanation is not possible in an ol forum lyk this..i advise u to go thru

HC Verma's Concepts Of Physics...Vol II Chapter No.38..

if @ represents the complex number

cos (pi/2n) + i sin (pi/2n),then lim(n tends to infinity (n|Im(S_n)| where

S_n= 1 - 2@ + @² - @³+ ........ - @^2n-1 equals equals

a)2/pi

b)pi/4

c)4/pi

d)pi/2

The value of

(from k=1 to 5)sin k

/11 =

a)(sqrt11)/64

b)(sqrt11)/32

c)(sqrt11)/16

d)(sqrt11)/8

experts!!!!!!!.............m waiting for the answer(s)

If a and b are the roots of px² + qx + r =0 then roots of eqn..

a) (p-q+r)x² + (q-2r)x + r = 0 are a/a+1,b/b+1

b) px² - qx + r =0 are a-2b,b-2a

c) prx² - (q² -2pr)x +pr -0 are a/b,b/a

d) px² + 10qx +100r =0 are 10a,10b

more than 1 answer is correct

but i dont havthe solns with me..plz solve
