Hello Sir, I want your help. I am very weak in geometry , so I wanted to take some advice from you about it. Please tell me what shall I do to improve it. Thanks.

@Michael Mendrin · 1 year, 4 months ago

well u've got lvl 4 n u r say'ng u r weak!! · 1 year, 4 months ago

Me too ! I am also weak in Geometry. · 1 year, 4 months ago

Well, @Rajdeep Dhingra Can you please post some more projectile motion problems in your free time? I @Swapnil Das would be indebted! ( Just trying to see what happens when you mention yourself!) · 1 year, 7 months ago

Thank you very much! · 1 year, 7 months ago

How to dethrone a complex cube root of unity from its complexity? This is a stupid short puzzle type made by me. · 1 year ago

by cubing it?? · 1 year ago

Correct. :P · 1 year ago

what would happen if we multiply it to zero? would it die!? · 1 year ago

Yes and then @Swapnil Das will arrange its funeral :) · 1 year ago

Lol, but you have to promise to pay the expenses :P · 1 year ago

@Joy Patel Instant action, isn't it? · 1 year, 1 month ago

Are you Swapnil or Swaplin? Or wait........ Are you Einstein?

All I know is that you are a high profile physicist. :3 · 1 year, 1 month ago

Why dont you come on fb? · 1 year, 3 months ago

I usually avoid social distraction and adore isolation with mathematics. · 1 year ago

Yeah! In 2013. I was the State Topper Even. I was studying in Rajasthan back then. · 1 year, 6 months ago

Oh, so nice to talk to a mathematical prodigy! Can you please advise me for RMO?

@Satyajit Mohanty · 1 year, 6 months ago

RMO is very elementary... If you're able to solve Level 4 problems here in Brilliant in Number Theory, Algebra, Geometry, Combinatorics, you'll top RMO :) · 1 year, 6 months ago

sata re?? kintu mu ta karipareni!! hardly 2-3 solved if i'm lucky.... i've 5 in all u mentioned...still find rmo problems difficult · 1 year, 4 months ago

Please dont discuss here. · 1 year, 7 months ago

Well, @Rajdeep Dhingra does FIITJEE prepare for RMO and NSEJS? · 1 year, 7 months ago

It makes U prepare for NSEJS but only a little for RMO. · 1 year, 7 months ago

Then I should join FIITJEE next year itself! · 1 year, 7 months ago

@Sravanth Chebrolu Hey Sravanth, Have you posted any problems on Projectile motion? Can you post some? · 1 year, 7 months ago

Yeah. You can check my set Gravity, but presently I am not working much with physics, if you really want some problems I'll post them soon! $$\ddot\smile$$ · 1 year, 7 months ago

Thank you! · 1 year, 7 months ago

Have U tried mine ? Come on Hangouts · 1 year, 7 months ago

I can't come on Hangouts for reasons, and yes I have tried your problems, and the alien Projectile problem was just great! · 1 year, 7 months ago

Have U tried Pizza War 2 ? · 1 year, 7 months ago

I was mistakened long ago! :( · 1 year, 7 months ago

I didn't get U. · 1 year, 7 months ago

I did the problem wrongly long ago, I meant. :( · 1 year, 7 months ago

@Sravanth Chebrolu Hi! Can you please let me know how are you so good at logic? How can I improve? · 1 year, 7 months ago

I think you must take suggestions from Nihar or Pi Han Goh sir or Calvin sir or Julian Poon sir etc. . .

They are lot better than me! · 1 year, 7 months ago

Remember the thoughts,

Imagination is more important than Knowledge. . .

Practice makes man perfect. . .

I think these two thinks did help me a lot! But, honestly, I don't think I am so good

Here are some tips to improve yourself:

• I recommend you to play chess if you would like to improve at logic.(I personally love playing the game!)

• You can practice questions on brilliant! That's the best way to improve yourself.

· 1 year, 7 months ago

Well can we play online chess? · 1 year, 7 months ago

Ofcourse! Can you provide me the link? But I can't do it today, maybe tomorrow after $$5$$ PM? · 1 year, 7 months ago

No, I was just asking if there is an online link for playing chess,.. · 1 year, 7 months ago

Yes here it (www.chess.com) · 1 year, 7 months ago

sorry now check. · 1 year, 7 months ago

I'm sorry, but I don't know any such website? If you find any do inform me! $$\huge\ddot\smile$$ · 1 year, 7 months ago

Sure! · 1 year, 7 months ago

Thanks! · 1 year, 7 months ago

@Nishant Rai Hello again, Sir!

Can you please suggest me some reference books for Class 11 Physics? · 1 year, 7 months ago

@Swapnil Das

After that, do NCERT Exemplar. You can get the pdf's from here . It contain's some very good, high level questions.

If enrolled in some coaching institute, go through their material thoroughly ( Do not jump form one coaching material to some other, they all contain the same thing, except the way they are written). · 1 year, 7 months ago

@Swapnil Das

I forgot to mention $$\text{Concepts of Physics Vol I and II - H. C. Verma}$$. Do it to clear and test your conceptual understanding of the subject. · 1 year, 7 months ago

@Swapnil Das After that, go for $$\text{Problems in General Physics - I.E.Irodov}$$ · 1 year, 7 months ago

I have already solved from problems from there in class 8. · 1 year, 7 months ago

@Nishant Rai pls post the solution to the problems. Thanks! · 1 year, 7 months ago

@Swapnil Das to all the questions i have posted?? · 1 year, 7 months ago

No Sir, the Kinematics ones up recently posted. · 1 year, 7 months ago

Not now, but will post after some members posts their solutions. I want to see how other people are attempting the same question. · 1 year, 7 months ago

Come on Hangouts · 1 year, 7 months ago

RD u there! Actually my internet connection has finished and I am on tab, so I will not be able to come before 15th . · 1 year, 7 months ago

Ohh.... . · 1 year, 7 months ago

I hope you would not mind talking here. · 1 year, 7 months ago

not at all . I can surely talk here. · 1 year, 7 months ago

Thanks, BTW I am learning Trig and Graphs. · 1 year, 7 months ago

Comment deleted Sep 19, 2015

Well, I'll surely try. Posting prob on tab is a hell. · 1 year, 7 months ago

@Nishant Rai Hello Sir! I just wanted to make a humble request. The standard of the problems you post on Brilliant is really great. I just wanted you to post some kinematics problems on B'ant( without trigonometry, but of high standards). Please take my request into consideration, and please help aspiring physicists like me. · 1 year, 7 months ago

@Swapnil Das Thanks! give me some time, i will surely post questions related to Kinematics. · 1 year, 7 months ago

Thank you very much! · 1 year, 7 months ago

Where did your Einstein go? · 1 year, 7 months ago

Haha, well which one do you like? The original pic or the Einstein? · 1 year, 7 months ago

Of course , Einstein. · 1 year, 7 months ago

Then I shall change it. · 1 year, 7 months ago

U called me ? · 1 year, 7 months ago

Yes, pls be my trig teacher and tell me how to start. · 1 year, 7 months ago

Just read 11th NCERT. It's great. · 1 year, 7 months ago

Will DAT be enough for both physics and math? · 1 year, 7 months ago

For physics it would be. But if U mean Problem Solving in Maths then U can practice from brilliant.

P.S - For NSEJS it is enough. · 1 year, 7 months ago

in which class u r · 1 year, 3 months ago

9th, Can you hangout me in G+? · 1 year, 3 months ago

bro, just email me your message... Ok?? · 1 year, 3 months ago

Aahh.. sure. I thought we could discuss Olympiad problems in the brilliant community we have made in g+. · 1 year, 3 months ago

Thanks , Sir! · 1 year, 7 months ago

@Sravanth Chebrolu Hey bro! actually the answer to the second question asking for remainder is 46. It is given in my answer key and I solved it too. · 1 year, 7 months ago

Can you ex plain that? · 1 year, 7 months ago

The last expression comes as x^2 -13x + 32 = f(x) · 1 year, 7 months ago

Understood! Dividing it by $$(x+1)$$ the remainder is, $f(-1):(-1)^2-13(-1)+32 \\ =1+13+32 \\ =\boxed{46}$ · 1 year, 7 months ago

Well, If u get some free time, Please post some problems on Newton's Sums. · 1 year, 7 months ago

Sure! But recently I am working on Combinatorics, I see to that very soon! I am building a new set don't miss it! · 1 year, 7 months ago

I will surely try to solve them and also popularize the set! · 1 year, 7 months ago

Thanks! But, I think I must leave now. See you soon! bye! · 1 year, 7 months ago

Oh! Yes. Sorry for leading you the wrong way.

The new function is actually, $$f(x):x^2-13x+32$$! And that when divided by $$(x+1)$$ leaves $$46$$. · 1 year, 7 months ago

No sorry in Friendship! ( if you accept me one) · 1 year, 7 months ago

Of course! You are by best friend on Brilliant! Who's understood me as perfectly as possible. · 1 year, 7 months ago

Oh, Thanks! I thought U would get frustrated by my foolishness! · 1 year, 7 months ago

Never! I am guy of very high patience. · 1 year, 7 months ago

That is really nice! · 1 year, 7 months ago

What is your favourite technique in all of mathematics ? · 1 year, 8 months ago

I love Fermat's Infinite Descent and also Simon's Favorite Factoring Trick. · 1 year, 8 months ago

Till now, my favourite is Fermat's little theorem.

What about you? · 1 year, 8 months ago

My favourite techniques are Induction and Invariance Principle.

By the way, I meant techniques, not theorems.

· 1 year, 8 months ago

If you ask about techniques, then induction will be my favourite! · 1 year, 8 months ago
