sir,
i am Viswanathan from TN.I have attempted IIT this time.i got 61/408.But i didn't go for coaching classes.i didn't prepare. it was really a surprise for me.i would have prepared for 18 days or so.i belong to TN stateboard.I have a hope of getting 90% in stateboard.u see our stateboard is too subjective and there are no entrance at all.the most worst in the world.i never used to sit and learn after my exams i started solving problems.know i am fond of asking doubts and solving problems.I didn't attend coaching for that too.I like only self study.so, can you tell me whether i can wait for 1 year and do self study?
please answer me soon......
thank you sir for your coming answer.

.u can view about me i joined on 8/5/12

it is an inspring story

superb this an inspring story for failures like me

eh frinds watch the link below we r given 0 marks for 2 questions in paper 2 -maths

thanx

isoprpylene?

you can download iist solution by many coaching institutes. IIST is a better than IIT in aerospace in my view..will u join IIST or IIT...reply

post yours!!!!!!!!!!!!at present 3000 r online each can contribute one formula

are you mad u r discussing a physics problem in zoology . that to reaching 50 comments to a simple problem without knowing the question!!!!!!!!!!!! first see the question and try it yourself otherwise post here properly @ tarun u r genius don't waste your precious time

issac newton used calculus for the first time

can anyone list the non integrable forms.I am searching for an hour.

@ pranab ah! its not equal it is proved are n't u aware of it

you all play i don't restrict.but u don't have rights to critizes others

please post more

integration of (tan x+ cot x)^2

answer is tan x-cot x+c

General Method

The divisor should not be too small. The smallness will give

rise to big quotients with several digits. This will lead to

complications.

Another method is to multiply the given number by another

small number cubed and find the cube root. Final answer is

calculated by dividing the result by small number

Example 4: Find the cube root of 2

We multiply 2 by 5

3

The new Number becomes 2 x 125 = 250

Find the cube root of 250 and divide the answer by 5 [

since we multiplied the original number by 5

Step 1

250 : 0 0 0

By inspection write down 6 and 34 as the first Q and R .

Since 216 is the perfect cube close to 250 and the

reminder from 250 is 34.

Step 2

250 : 0 0 0

108 : : 34

: 6 :

The dividend is found by multiplying the Quotient Squared

by 3 , 6

Step 3

250 : 0 0 0

108 : : 34 124

: 6 : 2

The second gross dividend is 340 , Do not subtract anything

from this, divide it by 108 and put down 2 as Quotient and

124 as Remainder.

Step 4

250 : 0 0 0

108 : : 34 124 196

: 6 : 2 9

The third gross dividend is 1240 , subtract 3ab

2

The third actual working Dividend is 1240 - 72 = 1168.

Divide 1168 by 108 and put down 9 as Quotient and 196 as

Remainder.

Step 5

250 : 0 0 0

108 : : 34 124 196 332

: 6 : 2 9 9

The 4

2 x 9 + 2

The 4

Divide 1304 by 108 and put down 9 as Quotient and 332

as Remainder.

Step 6

The number of digits in the cube root will be 1 , so the

cube root of 250 is 6.299

Cube root of 2 can be found by dividing 6.2999 by 5

The cube root of 2 is 1.259

3 ]2 X 3 = 1082 , 3 x 6 x2 = 72.th gross dividend is 1960 , subtract 6abc + b3 , 6 x 6 x3 = 648 + 8 = 656.th actual working Dividend is 1960 - 656 = 1304.
