    1. santosh says:

      61,64 ,82, is wrong answers

    2. monika says:

      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?

  12. sravanthi says:

    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.

    1. naveen says:

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

  13. sravanthi says:

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

    1. santosh says:

      above 85

      You can also send the questions of these answers with questions/answers and a photo of yours to Solutions at CSIRNETEXAM.com

      Thank you!

      1. nagaiah says:

        hallo sir

        Please send the csir maths key 2012.

    2. rasuprathap says:

      yours answer good and useful thanking you .

    3. anish says:

      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.

    4. monika says:

      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.

  15. sravanthi says:

    santhosh, above 85 is for jrf or lecturership

  16. Balu says:

    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

    1. M.D.U ROHTAK says:

      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,,

      1. sravanthi says:

        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)

      2. anish says:

        sir, L1 functions maynt be bounded always

      3. Aman says:

        42-answer is 1

  17. anish says:

    do anyone have an idea about ques 67, 72

  18. ranadip ganguly says:

    77-option 3 may not be correct.
    [0,1,0;0,0,0;0,0,0] has two eigen vector

    1. sravanthi says:

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

    please send the csir net mathematics key june 2012

  21. manish raj says:

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

    1. sravanthi says:

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

      1. manish raj says:

        avager cut of

  22. manish raj says:

    sory, 73-1,3

  23. rafi says:

    plz tell answers for maths

  24. ABDUL SAMATHU says:

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

  25. vikraman says:

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

  26. Amit sharma says:

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

    1. Aman says:

      LS-72, JRF-82

  27. sudarmani says:

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

  28. Lata says:

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

  29. sravanthi says:

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

  30. Lata says:

    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?

  31. Lata says:

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

  32. bhabesh says:

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

  33. bhabesh says:

    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

    1. sravanthi says:

      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.

  34. sravanthi says:

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

  35. Lata says:

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

  36. bhabesh says:

    result will be given in between 22-26 august

  37. adil says:

    what abt Q66 i think answer must be 2 and 4

  38. adil says:

    what abt Q66 i think answer should be 2 and 4

  39. Lata says:

    66-1 is also correct
    RHS=log(xy)/2 then take e power both the sides and check inequality for any x,y>0.

  40. adil says:

    log (x+y)/2≤(logx+logy)/2
    =logxy/2
    =log〖(xy)〗^(1/2)
    (x+y)/2≤〖(xy)〗^(1/2)
    But, G.M ≥ A.M

  41. Lata says:

    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.

    1. devi says:

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

  42. adil says:

    yes, sorry.
    it is A.M greater or equal to G.M
    now anybody tell me what are cutoff scores

  43. rajesh mishra says:

    hi.ans to each other vary.confused

  44. rajiharsha says:

    hi i cannot download the question paper …
    there is no option to download …

    thanks in advance

  45. vidya says:

    please send me csir 2011 dec maths qns with answer

  46. samm says:

    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

  47. rahul mangla says:

    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.
