good work !!! thanks a lot !!!!

Ok i did not start my IIt preparation till now........ Its just that i was doin my 11th n 12th portions(State board) . Suppose i start my proper IItJEE prep from today. Preparation in sense study from prescribed books for jee . Do u guys think i can still make it to the IIT's or may be even BITS or NITs ?

gud work .........

ya ya i did some mistake ........

you get the answer to be (1/4 , 0)

A (-1,0)

B (1,1)

Let P(x,y) be a point equidistant form A and B

So

PA = PB => PA² = PB ²

Use the distance formula d = sqrt[ (x1 - x2)2 + (y1 - y2)2]

Find PA PB equate

we get an equation

then do simultaneous equating of the euation we got and 4x+5y=4 .

A (5,3)

B (3,-2)

Let P be (x,y) movin such that PAB is always 9

Area of a triangle = 1/2 |x₁(y₂-y₃)+x₂(y₃-y₁)+x₃(y₁-y₂)|

9 = 1/2 | 5(-2-y) + 3(y-3) + x(3- - 2)

18= |-10 -5y +3y -9+5x|

37 =5x - 2y or 1= 5x - 2y

Me got only the pic

cudn't crack the funda

........

do try answerin this ppl .............

Thanx a lot ppl !!

If i put 4-5 hrs of quality hard work ... is it still possible for me to crack IIT this very year ?

I was into the usual state board sylabbus.... did not prepare particularly for IIT as such till now .... Got these 14 module books from brilliant tutorials a few days back .... if i am able to put in 4-5 hrs of hard work everyday ....... how much is the possiblility of me crackin IIT-JEE... Is it a good idea to drop 1 year and take chances........ ???

Do write in watevr u feel ............

@ him ............ thanx for makin it way toooooo easy !!
good ans !!

can you do it without the formula ? cos this prob is given before the formula is given

n the ans is -1/8

oops guys ...... typed the q wrong !!!!

its only

cos /7 . cos 2/7 . cos 4/7

who answers correctly first shall be accepted as correct

ok here is the problem

cos /7 . cos 2/7 . cos 4/7............

answer with steps pls.... I tried it but i'm goin wrong somewhere so i'm not gettin the right answer.......

oops guys ...... typed the q wrong !!!!

its only

cos /7 . cos 2/7 . cos 4/7

Thank you all !!!!

whats the logic to solve these kind of problems like the one given below?

Find sum till n terms:

3.7.11.15+7.11.15.19+........................

BASE?? I herd its damn good!!
But if you have decided to drop out then i feel You can give quality time in your house itself n study as it'll be ur second attempt.
But if you wanna go for coaching centers then BASE is good.

I am class 12.I have this Brilliant tutorial material for preparing .Started preparin only from April this year. My question is the Brilliant tutorial material enough ?

If no then what are the other books i shud refer/study from?? plz answer....cos these suggestions of yours are precious for me !

Consider the time i have too... only 7-8 months!!

a = 1.2 kg
b = 5.42g = 0.00542

see its very simple
i when we add we get 1.20542 ..but in a only the first decimal figure is significant
therefor all the other figure after the second decimal are insignificant.
now we have to round off the second decimal figure 0. The digit next to it is 5 n 0 is even ... therefore it is left unaltered . Thus the answer is 1.20 kg.

hehe thanx!!!
