I used some simple analitical geometry and get the side of the square is 38 and thus the area is (38)2=964
Log in to reply
yes
how did you do it
Log in to reply
Just put the triangle in the Cartesian diagram with the coordinates are (0,0),(4,0) and(0,8)
Log in to reply
But how to maximize
Log in to reply
The largest square in the triangle is when the square's coordinates are (0,0),(0,x),(x,0)and(x,x) with (x,x) lies in the hypotenuse .

so
Please could you give the full solution
Log in to reply
Since (x,x) lies in the hypotenuse, it lies in the line y=−2x+8. Then x=−2x+8 3x=8 x=38 So the side is 38

Thanks! a lot
See this problem.

Could you elaborate his solution @Calvin Lin

You should comment on his solution and ask him to clarify.
This the procedure to do this kind of a sum:
Let the side of the required square be a.
Length of the remaining parts of the two legs are respectively 8−a and 4−a.
So the total area which is 21.a.(8−a)+a2+21.a.(4−a) will be equal to 16 (the area of the whole triangle)
Solving the equation you get x=38
and hence the area is 964

bhaiya in which school u did ur class 10th is it a dummy one
Log in to reply
I did half 10th in DPS Mathura Road and half in DDPS.
Log in to reply
why so is ddps a dummy and cbse board and now in which school
sorry for 'why' i am not interested in that but what u think about dummy schools because i think one can't get enough time to prepare for olympiads and all from the pulls and pressures of the schools
pls rajdeep bhaiya tell me about moderator and how to be so
Rajdeep bhaiya in which school u r currently studying.is it worth to join a dummy school for 11th and 12th
Log in to reply
It is really difficult to answer such questions. Such things are based on school to school , child to child so you really have to decide it yourself.
Log in to reply
u r absolutely correct is shiv jyoti in rajeev nagar,kota a dummy one
Log in to reply
yeah
Log in to reply
are u still in kota
IS IT ADVISABLE TO PREPARE FOR IMO (HBCSE )ONE WITH JEE PREPARATION .WHAT U WOULD RECOMMEND OR SUGGEST TO PURSUE BOTH OF THEM OR EITHER OF THEM i.e. latter or former one
Log in to reply
If in class 11 then should do JEE else both.
Log in to reply
not in 11 th but as of now getting my hands cleaned off the boards i am promoted to class 11 and were u able to make out to inmo if so then suggest me books
i actually want to pursue physics as my interest as future career especially to do some sort of research and truly speaking i also want to master mathematics to migrate to higher physics as well as without latter it would be almost impossible to do so .and i know that whatever is in imo is for mathematics and in modern physics or even in classical one demads a nice hold over calculus which is not at all in imo
Bhaiya which book would be better for physics halliday resnick and krane,halliday,resnick and walker or university physics by sears and zemansky or physics for scientists and engineers by serway and jewett regarding ipho and for proper understanding
Log in to reply
All are same.

@Rajdeep Dhingra Bhaiya i want to know if it is possible to pursue studies from shiv jyoti convent in kota from another city and waht is the fees of ddps kota class 11 pcm 1 month. pls can u give me the(URL) link or list some dummy schools with minimum fees range.pls reply asap .pls help me
Log in to reply
pls answer
I don't know , but DDPS , Shiv Jyoti , Maha Bharti Kota , these all are dummy.

Log in to reply
can you ask from someone fees of DDPS for me class 11 because it is no longer possible for me to get all information like fees from here Lucknow.I am only dependent on you and these two websites brilliant and quora for my answers .
Log in to reply
You can call them up and ask. Fee Structure
DDPS is a dummy therefore i think not even once in a month one goes there during pre-board or exams one has to go there or i if i am wrong then pls do write correct info. is it required to attend the school weeklies i.e. 1 day in a week.
Log in to reply
I don't know these things , but I think you have to go once a month or something.
Log in to reply
How many times you attend the school i.e.(DDPS) once in a week or in 2 weeks period.I wanted to know it on an average which means how many days per month.
Log in to reply
I don't know so much detail. Just call them and ask.
DDPS

aap allen ke hostel me rehte ho
@Rajdeep Dhingra pls help me in this question if sum of three unit ,coplanar vectors is equal to 0 i.e. Â+Ŷ+Ê=0.and if vector p,q and r are parallel to vectors A,Yand E respectively.p.q and r have integral but different magnitudes then |vec p + vec q + vec r| can be = to options:
1.)root 3
2.)root 2
3.)1
4.)0
ques type (ONE OR MORE IS CORRECT)
Log in to reply
All are correct.
Log in to reply
can u explain how
Log in to reply
pls explain me asap
Log in to reply
why are u silent pls if u know the thought process explain me this
Examples , p = 1+sqrt(3) A, q = 1 B, r = 1 C p= 1+sqrt(2) A, q= 1B , r = 1C p= 2 A , q=1B , r= 1C p= 1 A , q= 1 B , r = 1C
Log in to reply
can u write which corresponds to which option like ur first example corresponds to which one it would be easy to check
Log in to reply
It is the order only.
Log in to reply
thanks that i made
they have same magnitudes atleast two of them have if u have solved then pls explain or reply .pls reply
PLS REPLY IF U HAVE SOLVED IT IN EXAMPLES THEY HAVE SAME MAGNITUDES AND ALSO IN YOUR METHOD THEY ARE HAVING SAME MAGNITUDES A,B,C=0. ATLEAST QUES. IF QUES. IS LACKING INFO. ACCORDING TO ME IT IS LACKING SO.
pls explain me well you can also give me link of imgur if written on copy
@Rajdeep Dhingra can you write what you thought for solving the problem or u directly thought their magnitudes can be all of them we have to select them so that all of them adjusts for answer to be all respective options
@Rajdeep Dhingra can you write what you thought for solving the problem or u directly thought their magnitudes can be all of them we have to select them so that all of them adjusts for answer to be all respective options
PLS REPLY
@Rajdeep Dhingra i think you have done a mistake their magnitudes have to be different pls reply if you got a new intuition or thought process behind the problem .the same ques was published by resonance coaching in their test paper for jee advanced
what i should do to get the answer of that vector problem in my book .i don't know how to post a multi correct answer type questons
@Rajdeep Dhingra I want to buy EM Purcell and Morin Elcetricity and Magnetism in Paperback edition or to download it ;hardcover edition is there or pls bhaiya just share it if you have through internet i.e provide me the link
Two particles of mass m and M undergo uniform circular motion about each other at a separation R under the influence of an attractive constant force F. The angular velocity is ω radians per second. Show that R = (F/ω2)(1/m + 1/M)..
