61,64 ,82, is wrong answers

Plz explain the ans of 80th ques.how the c option is correct bcoz ot should be correct if we fill n=1/3but we given in ques.n>=1?

hello santhosh, for the question 42, we are going to get two solutions in the terms of ‘e’ powers, V is a vector space of bounded solutions of differrential equation, but we know that ‘e power x’ is not a bounded function, so i think answer will be 3. if ,u know explanation pls, post here.

answer is 3 of 42 with the same explanation as urs that e power x isnt bounded

also can any one guess what can be the cut off marks for lecturership for this time

Thank you!

hallo sir

Please send the csir maths key 2012.

yours answer good and useful thanking you .

for 42 , we are asked about bounded sol. not just sol. and e power x isnt bounded, so i think answer to this is 3, it contains only trivial sol.

Can u plz explain ques no.80.how option 3rd is correct bcoz its only correct when we filln=1/2 but we also given n greater than equal to 1.

santhosh, above 85 is for jrf or lecturership

42-3 {o}is the only bdd solu 61-2,4 cos|x-5|&|x+10|cube r diffble at5,-10 .75-2 By caleyhamilton tiheorem at most n matrices r LIo

bhai shab kis dunia main rahte ho 42 ka answer 1 hoga because solution are e ki t and e ki 3t hoge which are LI….. 75 ka answer n squre hoga because c ki dimension n squre hai,,

ofcourse sir, even though they are LI ,they are not bounded (e power x is not boinded above).so, only bounded solution is u=0.(see the question,they said v is set of bounded solutions of differential equation)

sir, L1 functions maynt be bounded always

42-answer is 1

do anyone have an idea about ques 67, 72

77-option 3 may not be correct.

[0,1,0;0,0,0;0,0,0] has two eigen vector

(0,0,0) is not an eigen vector

67-1,2

please send the csir net mathematics key june 2012

csir net-72-75 /jrf-82-85

what are these numbers monish raj?u want answers for those questions or these indicating cutoff?

avager cut of

sory, 73-1,3

plz tell answers for maths

i need question paper and answer key plese send me by Abdul samathu

i need question paper and answer key plese send me by vikraman

This tym cutoff will be as—- ls-80 and jrf-90

LS-72, JRF-82

please send csir question paper and answer keys for mathematics, June 2012

89-3,4.because number of 2-sylow and 3-sylow subgrp not 1 so not normal,so 1,2 are incorrect

hello… csir published the answer key in its website.so,go ahead.

yes i saw it after writing my comment.

i still want to know how can 75-2,3 both correct .in 2 option atmost n is there and in option 3 n square which is greater than n.

in 74-2,4 if we take square of order 3 having all the elements 1 then option 2 is false.

expected cutoff and date of result?

i mean to say square matrix of order 3 having all elements 1

can any body say anything about cut off after csir publishing the answer key in maths ? i will get 85.25

can any body say about the cut off as csir published the answer key ?according to answer key i will get 85.25 .is there any chance getting ls since maths paper is not so hard like last year december

yaah, so many expecting that the cut off for LS will be 80 marks. so,iam also hoping for best.

but, only few saying that it will be above 90.

if any body have any idea about cutoff ,plz post a msg here.

when was csir net june 2011 result declared.(Date of result)?

result will be given in between 22-26 august

what abt Q66 i think answer must be 2 and 4

what abt Q66 i think answer should be 2 and 4

66-1 is also correct

RHS=log(xy)/2 then take e power both the sides and check inequality for any x,y>0.

log (x+y)/2≤(logx+logy)/2

=logxy/2

=log〖(xy)〗^(1/2)

(x+y)/2≤〖(xy)〗^(1/2)

But, G.M ≥ A.M

i think by mistake you wrote g.m>=a.m .[ (x+y)/2-a.m , (xy)^(1/2 )-g.m ]

actually it is a.m>=g.m and equal only for x=y.

and yes if we see this inequality option 1 seems incorrect now.

and what is your saying on my question 74 and 75.

i think answer of question 75 is option 3 only which is n square.

yes, sorry.

it is A.M greater or equal to G.M

now anybody tell me what are cutoff scores

hi.ans to each other vary.confused

hi i cannot download the question paper …

there is no option to download …

please suggest me , how to download the maths question paper …

i can only see the question paper when i open the question paper ?

thanks in advance

please send me csir 2011 dec maths qns with answer

hello frnds

how can i prepare for csir net

my sub is maths

and im very nervous

…so pls frnds give ur valuable suggestion

for this tough exam

waiting for ur reply

best wishes of deepawali

Can somebody pls refer good books for preparing for Complex Analysis…

I do not know even A B C D of complex analysis…so i need a book which can make the concepts clear and help me in CSIR NET Mathematical Sciences prepration.
