    how can u cancel cos2x to cos2x if both the terms are positive in denominator

    • @sanjaytaji8727
      @sanjaytaji8727 7 лет назад +17

      answer of question no. 1 is 2/6 means 1/3 definatly...........and 2nd one is correct

      @mangeshmahajan4445 7 лет назад +70

      not 1/3, it is -1/3

    • @kanhiya7682
      @kanhiya7682 7 лет назад +5

      its simple way of solution in denominator when -sinx will multiply with x square then we get -x square sinx after it this - sign will multiply with + cos x 2x then it become - cos 2x 2x thenafter starting of 2x cosx is positive then easily this will be cancel out - cos x2x ,+cosx 2x

      @khanzoya6203 6 лет назад +9

      Kanhiya Kumar
      But see in the denominator when we do the differentiation of x square sin x we get the negative sign only with first term.. like this -x sqaure sin(x)+cos (x)2x and this cos (x)2x is positive not negavtive so it can not be cancelled with the ist term of our denominator i.e 2xcos (x) which is also a positive.. term

  • @smitakullu6549
    @smitakullu6549 7 лет назад +17

    Sol. of question no. 1 is -1/3
    Sol. of question no. 2 is 3/2

      -1/(1+ x ) its diff. Is 1+x (0) - {(-1)(0+1)} / (1+x)^2 = - 1/(1+x)^2 and when we put x=0 we will get - 1 hence sir is absolutely right in question no. 2
