@GauravAggarwal see the argand plane is just a kind of visualisation for complex numbers as the number line is for reals. So why did we chose another dimension, the y axis for representing the "imaginary numbers"? Because you cannot put them anywhere on the Real number line!

@blue I finally went back to old coaching. Actually our chemistry teacher teaches everything in so much detail that it becomes difficult to follow regularly.

@blue my parents were against self study, and they told me to join a coaching. buying a lecture will cost around 10k more, already have spent 80k on fees of coaching! i guess its foolish but cant help that

I actually need some online OC lecture because OC is very tough for me. I basically am able to attempt only mugging up type questions!

@samjoe buy mugging up, you won't be able to get too far. :-(

that i know very well :~)

hmm you are right, as they said in etoos lecture intro. but good thing about the lecture is that we can play it again and again! With coaching once lost it is lost. (- This line is by mohit tyagi in his online video :P)

Is NCERT enough for JEE Advance for Inorganic Chemistry ?

@AakashKumar Not enough, do also the previous year questions!!

they ask some out of course things like HOMO LOMO and Orbital Equations of various orbitals.

Are you talking this year JEE advance paper ?

Do NCERT properly. I have seen text in NCERT chemistry book is very well written, although it may not be covering full jee syllabus

@Blue I read JD but didnt find HOMO LOMO thing

I did find Orbital equation, oh wait I havent probably reached that section yet!!

The black one

Should I also dump my OP Tandon Inorganic ?

Ok .Please recommend be books for all three chemistry section .

@samjoe if you want the lectures of your teachers at coaching do this: keep your mobile in your shirt pocket, with the camera facing the teacher. Record video of the whole class. It's done!

lol this is a very nice idea indeed!

I will be giving 2018 JEE so I think I didn't have much time .

Brilliant rather ill buy a small camera device and, tadaa!

Yes ,I am taking .

At Vidayamandir .

that was suspiciously quick. who have you been stalking lately :-}

@AakashKumar New delhi?

Yes

safdarjung or pitampura

Pitampura

hmm I am also at Vidyamandir but New Delhi! Are founders teaching you? or others? Narendra sir?

@samjoe one of my batch mates at fiitjee used to do that, but somehow was caught and kicked out! He used to upload all lectures to you tube.

poor fellow

No ,I think founder not teaching any dropper batch there this year .

I wonder why physics and chemistry dont have free lectures like mohit tyagi has for maths :-\

At our coaching there is also warning of No recording of lecture .Doing so will get you kicked .

This year they didnt even ask a single question @blue

or probably i missed it :D

imp chapters at the end? nice strategy :P

Yes .Mohit Tyagi lectures are outstanding . One of the best teacher .

well actually it is nice, jokes apart @blue . else we forget them easily!

@Blue I started qualitative in the end too, manajed the anions, then got frustrated and left it entirely

Its just frustrating. one day u learn and then when we revise the next day, its wiped out :/ or it gets mixed with other things

Can I ask my doubts here ?

@AakashKumar always

In which college you are ?

1.22 ,I tried it by the equation of trajectory but can find the coordinates.

Yes I did it with this method .I was actually trying to do it without shifting the axis.

Taking orgin as Point of projection .

@blue forgot to ask: how was thy classes? In which building are you having classes? Is it the tallest building in the campus? (Asking this because my father asked, he is from jadavpur, civil engineering. In his time, all engineering classes were held in that building.)

@blue are thee giving jbnsts this year?

@Blue oh yes, I forgot that.

I chose my centres jadavpur and presidency. Father strongly recommends jadavpur as it's walking distance from my house. Mother prefers presidency due to her nostalgia (I also have a bit of this nostalgia, as it's a place closely associated with netaji, jagadish bose, satyendranath bose, prafulla Roy...)

@Blue centres for examination of jbnsts, not for ug

@Blue physics department still has good teachers.

@Blue thanks!

@Blue that's a problem in almost all science universities in calcutta

Yeah did it at last.

@Blue I had mailed iiser Pune physics department Chairperson regarding all that problem I was telling you last day. Secretary wrote a lot of harsh words. I'm mad at him. I'll take revenge some day :-|

1.36 ,To come back again at its initial point it must hit at its highest point .So half of time of flight should be answer .

@Blue in a separate chat, I was telling you about marks in humanities... I had asked him whether only passing would do enough, because if so, I would have looked forward to iiser. He said that since I'm talking about only passing in interdisciplinary topics, one day I would also talk of only passing in Physics. This made me horribly mad.

@Blue true, but I need to steer in the right direction. Fixing an aim is good, though building castles in air is equally bad.

@JohnRennie how can we help thee? :-)

Just passing through :-)

@JohnRennie I see.

I was just checking the room out for a potential new member @Abcd

Hey! 2019 aspirant here!

@AakashKumar are you a 2019 JEE aspirant too? or 2018?

@Abcd he's 2018

@WrichikBasu Okay. He must be revising 11th Kinematics if I am not wrong

@Abcd perhaps.

@Abcd how are your preparations going on?

@Abcd I am dropper .

@WrichikBasu Chemistry and Maths - fine, I like these subjects but Physics :(. I am already lagging behind in physics. We have started with Friction in the coaching

@AakashKumar Okay.

My physics and maths is fine .My chemistry is very bad .

@Abcd man, how can you lag in Physics? That's the greatest of all, perhaps. Think big, think cosmos.. think small, think quantum. So, physics is everywhere!

@AakashKumar chem depends hugely on mugging up, though after understanding of course.

@WrichikBasu I am not well connected with nature, maybe that's the reason

@WrichikBasu Chemistry is more than simply mugging up. I love it. It's the subject that makes the most sense.

@Abcd true. It's because of chem that we are living

yes

Atwood machine means the simple fixed pulley system, right?

@WrichikBasu See the equations of tension en.wikipedia.org/wiki/Atwood_machine

@WrichikBasu 2018 or 19?

@Abcd was 2019 at one time, but now left completely, though interested in solving problems of that level. I'll take pure science and not engineering, so jee is not good for me.

@WrichikBasu Os so you are my age? I am 16.

@Abcd I'll be 17 in September.

Ok

@WrichikBasu So you will give KVPY ?

@AakashKumar yes, but not with great importance. At iiser or IISc, I'll have to study interdisciplinary topics like biology and humanities for 2 and 3 years respectively. I don't want that at all.

I'm looking forward to calcutta universities like Jadavpur, presidency and the like. I'll later aim for jam.

@Blue well, well. Firstly, the level of education in calcutta is not that bad, as you think it is. I've spoken to several seniors who have joined MSc in iit through jam or JNU, or have been doing PhD in iit for last 1 or 2 years.

They've all studied from jadavpur or presidency, and they say that no one has any problem in coping up with syllabi. The one in PhD says that she was much better by studying here, because many of her colleagues, who are doing research under the same guide, are not even as good as her and her friends from here, because they've been busy in interdisciplinary topics,

while here in calcutta, one can focus on the hons subject and treat the pass ones as less important for the exams.Secondly, good physicists should know topics other than physics, but it's a wring notion if you think that these can be studied only by giving semester exams.

Giving an examination any subject does not make you knowledgeable in that until you study it with heart, and I know I'll not be able to study humanities with heart, which means most of my labour will go to a waste.

It's similar to the case which I being forth in school almost everyday: you cannot study bengali by writing questions and answers. Even Rabindranath was against this. So, I want to focus on my favourite topics more.

However, I believe it's useless to talk about these now. I haven't even given kvpy, so there is no assurance that I'll get in any iiser at this point. Let's live in the present, as you suggested a little while ago :-)

@Blue good night! You are in a good position, my night doesn't come before 2 am :-( (study isc till 1:45 and then about 10 mins of qm)
