  1. please check this question in pieas test question no. 4
    correct if it's wrong,plz plz
    f(x+1/x)= x-1/x => solution is,
    let f(x+1/x) = y,
    then,
    y=x-1/x
    y=[x^2-1] / x
    xy=x^2-1 (By cross multiplication)
    taking derivative on b.s;
    x.dy/dx+y = 2x-0
    or, dy/dx=[2x-y] / x
    as dy/dx=f(x), and putting the supposition,
    so, f(x) = [2x-(x-1/x)] / x
    =[2x-x+1/x] / x
    =[x+1/x] / x
    =[(x^2-1)/x] / x
    =[x^2-1] / x^2 (answer)

  5. from f(x) = [2x-(x-1/x)]/x
    =[2x-x+1/x]1/x
    =1/x[x+1/x]
    =1/x[x^2+1/x]after taking LCM of the terms in bracket
    1/x(1/x)[x^2+1]
    x^2+1/x^2 ans

  22. Please explain maths question no. 5

    ReplyDelete
  23. I think the question is a little wrong.. Firstly it says 2 m and 9 cm, different units and then no units in the answer so one can't really decide which unit to give ans in..

  29. maths q no 13 answer is d= o , zero distance is the minimum distance between the parallel lines.

    ReplyDelete
  30. in q no 14 if question is correct like x^2+y^2+2x+6y=0 then answer will be y+1=0

    ReplyDelete
  31. physics portion q.no.2 solution: work(input)=F.S = 50N. 5m=250J
    work(output)=F.S=240N.1m=240J
    And as effeciency%=work(output)/work(input)=(240J/250J)x 100=96% efficiency
