How's your maths paper

Again out of curiousity, I am posting this note adressed to all my friends who are giving 12th Boards.

How's your maths paper and how much are you expecting.

Again one can discuss anything here.

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

  • Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
  • Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
  • Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
  • Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

The paper was easy but I had only 5 minutes left to revise. I think I got every question correct with all necessary steps but as I couldn't revise properly, might lose some marks in careless mistakes. Definitely 95+. Hoping for 98-100.

definitely above 90, only place where i might lose marks are the question which was asked to be solved by matrix method, Though i did solve it using matrices only by some how converting it into a matrix problem . what about you?

Mvs Saketh - 4 years, 7 months ago

I am expecting around 99/100 if everything I have written contained no silly mistakes well 1 marks I am losing because in a 6 marks question after completing solving at last I wrote the answer as 2(2+2)=222(\sqrt{2}+\sqrt{2})=2\sqrt{2}

Also is this your actual photo, you have as your profile pic.

Can you please tell question number, i do not remember ever writing 4(21/2)4 ( {2}^{1/2}) in answer sheet,

Yes it is, My JEE main profile pic

@Mvs Saketh I had Set-1 Q21. Minimum value of OA+OB.

You look quite a big boy, your image doesn't look like that of an 17 year old boy.

@Ronak Agarwal oh its fine then, either that question wasnt in my set or maybe it was in option,

Actually, it is camera effect, i am just 174cm long , shorter than you as well perhaps.

And, no, i did the Miscellanious exercices from CBSE before board exam and two to three integration questions were from there only, I do not know why some of these parents demand retest because their kid is an idiot . Infact, i finished it 40 mins ago and rechecked it twice, and they say time was low, infact some were telling me to ask for retest as well

@Mvs Saketh I am quite a short kid my height being 166 cm. You were very fast, although the paper was easy, I just finished 10 minutes before.

Also I was not commenting on height, I was commenting about age.

Ronak Agarwal - 4 years, 7 months ago

Log in to reply

@Mvs Saketh You think 174 cm is SHORT ??

Both of you are really my "Bhaiyyas" in terms of height . Btw I am 164 cm .

A Former Brilliant Member - 4 years, 7 months ago

@A Former Brilliant Member I am 166 only, among my friends I am the shortest, way shorter than each one of them. I am joked too much about my height.

Ronak Agarwal - 4 years, 7 months ago

Log in to reply

@Ronak Agarwal Yeah , I can understand . I am not made fun of , but then again , I am indeed among the shortest guys here .

A Former Brilliant Member - 4 years, 7 months ago

@A Former Brilliant Member just tell them you are not short, just trying to minimise your surface area like a bubble

@Mvs Saketh Seriously no! Physics and I are not made for each other , so I guess I'll refrain from a Physics excuse !

A Former Brilliant Member - 4 years, 7 months ago

Log in to reply

I think, I will definitely score in between 95 and 99.

Not sure if I have done the question of getting expression 'A^2 -5A+4I' given matrix 'A' correctly, I think I have copied 'A' wrongly from the question paper.

Karan Siwach - 4 years, 7 months ago

Just wanted to ask, are there people out here who are having Physical Education as their 5th subject ?

If yes, then please tell how are you preparing for the exam ?? I am just reading the chapters from the book, will it do ?

Karan Siwach - 4 years, 7 months ago

Log in to reply

The paper was very easy for me and almost all of my friends and classmates. I do not know why people are saying that it was tough. Strongly believe that there was some difference between my question paper and yours. My qp code is 65/2/MT. A lot of my friends finished almost 30 min before time. @Ronak Agarwal

I am talking about CBSE board paper, people are calling that tough . Are you from CBSE board or some other one.

Ronak Agarwal - 4 years, 7 months ago

Raghav and I are from CBSE.

Shashwat Shukla - 4 years, 7 months ago

Oh my god! Of course I'm in CBSE!

Raghav Vaidyanathan - 4 years, 7 months ago

Log in to reply

Definitely 88-90 ,Will only loss marks if there are any silly mistakes or calculation error..

Also On the difficulty of the paper,for us preparing for advance the paper was not that challenging but for the ones who have taken Maths as A fifth subject it was a disaster..

I remember a girl seeing a girl crying during the exam..

Roopesh Must have seen it too.We were in the same room..:3 :3

But All left is IP which is a very interesting Subject..What are you planning to Study???Ronak Agarwal And Roopesh..

Since I know only two of you having taken IP on Brilliant..

Vraj Mehta - 4 years, 7 months ago

Log in to reply

No , I didn't see anyone crying . You see I had my own problems to deal with .

Would you mind writing the initial of the one who was crying ?

Seriously , YOU are going to study IP ?? I am just going to read the Chapters 1,2 and the last Chapter (was it 16th ?)

A Former Brilliant Member - 4 years, 7 months ago

Log in to reply

Hmm , I think I'll get between 85-90 (yes , I had a definitely bad outing there)

But I'm just focusing on JEE Advanced right now , so I think it's no big deal .

A Former Brilliant Member - 4 years, 7 months ago

Log in to reply

Disastrous. I don't know why but I skipped past the binary operations 6 marker. I literally didn't see it. And the sad thing is that it probably was the easiest 6 marker of the lot. Expecting anywhere between 85-90.

Pratik Shastri - 4 years, 7 months ago

Yes, you'll definitely get 90

A Former Brilliant Member - 4 years, 7 months ago

Hmm, lets see.

Pratik Shastri - 4 years, 7 months ago

I am expecting above 90. The sad part is i realized two of my mistakes yesterday only. The paper was kind of moderate but difficult as compared to last year's paper.

Well, everyone can pretty much add 2-3 marks to their expected score. http://www.thehindu.com/news/national/cbse-maths-exam-board-mulls-grace-marking/article7011799.ece?mstac=0

I'm expecting above 90 and i think, paper wasn't tough but yes, bit lengthy.

@Ronak Agarwal @Vraj Mehta @Azhaghu Roopesh M @Mvs Saketh

Guys, can you please tell me your question paper codes? Not just the set number, but also the code, mine is 65/2/MT. I have been running into a lot of complaints about the exam wherever I turn, even in the newspaper, there were two separate articles about it. Please do reply.

Raghav Vaidyanathan - 4 years, 7 months ago

I didn't give the exam, but I've seen one set 65/2/2/F. One question was wrong in it. Q20 first part.

@Azhaghu Roopesh M @Siddhartha Srivastava @Ronak Agarwal @Mvs Saketh This paper must be the easiest one.

@Raghav Vaidyanathan You better not be kidding me ! That's too easy , really .

See the note that I posted , my paper was relatively lengthy . I'm sure you'll agree .

@Raghav Vaidyanathan Hi The paper we got in Delhi was different from this and for me it was not difficult but lengthy. got no time to revise I did some very stupid mistakes ( like 3 X 2=5 due to which i lost 1 mark ) expecting around 93-95.

Can anyone post solution to xcosx+sinxdxx(x+sinx)\displaystyle\int \frac{x\cos x+\sin x \mathrm dx}{x(x+\sin x)}

Pranjal Jain - 4 years, 7 months ago

Log in to reply

I know the answer to the problem with the minus sign in the numerator but not this one.

I have the answer as :

I=xcosxsinxx(x+sinx)dx=(xcosx+x)(x+sinx)x(x+sinx)dx\displaystyle I = \int { \frac { x\cos { x } -\sin { x } }{ x(x+\sin { x } ) } dx } = \int { \frac { (x\cos { x } +x)-(x+\sin { x } ) }{ x(x+\sin { x } ) } dx }

I=ln(1+sinxx) I = \ln { (1+\dfrac { \sin { x } }{ x } ) }

Sorry but I don't have the answer to your problem.

Does anyone have I.P previous year question paper along with the solution(all sets). Can anyone send the link regarding the same?
