2:05 AM
I guess I am super late because I was busy in the evening with some work :(
anyway, samjoe has said pretty much everything that I would have too
physics was ridiculously easy
chemistry had nice questions on organic (lots of steps and reagents!)
and maths was also okay enough
RIP single integer. Welcome subjective questions.
2
which were obviously lengthy also because you had to calculate till two decimal places

5:11 AM
reagents all from ncert?
yeah rip single digit welcome subjective questions....iit comes back again/

Many students made that mistake. 4 instead of 4.00
 
Sid
Not surprising at all..
 
hmm, I think even I'd have made that mistake :P
But no.. FIITJEE Aits pattern, so I wouldn't have made that mistake
@Sid Its sad to see them lose marks because of this :/
 
Sid
Well, if someone doesn't read the instructions carefully, that's what happens
 
Who cares about the instructions in any paper.- boards, school exams, jee etc...
Just no one.
Everyone expects the same old thing to be written there.
 
Sid
Exactly! THat's why people make errors.
The first error being not reading the instructions

@JohnRennie sir are you there?

Q: How was these 8 equations derived?

Akash. B$$(a+b)^2=a^2+b^2+2ab$$ I have been studying this since my fifth grade ,I have also used this equations for many times in my problem . My question is on what basis this equation was derived?not only this equation there 8 equations for solving complicated problems. So guys can you tell me how was ...

@Akash.B You know multiplication(you said you are in 10th grade iirc), dont you? Please use distributive property of multiplication and try to derive it yourself.
And which 7 other equations are you talking about?
hmm, you have edited now to add the other 7..
 
@Abcd yes
 
Sid
Hmm, just so you are clear, all these equations are only true for Real Numbers
 
@Sid what about geometry?
 
Sid
...what?
 
@Sid how was the area of cone was derived?
 
Sid
8:02 AM
As in? You just find the Area from integrating.
If you can't bother to remember their formulae
 
@Sid I want to make it more easy to study
 
Sid
does this not help?
