    @10:13 since outer loop has y and inner loop has x so in each ordered pair first element is y and second is x but by mistake i have considered first element as x and second as y......
    @10:13 i said 1 is greater than 1 , 1 is greater than 2 and so on
    but i should have said 1 is lesser than 1 , 1 is lesser than 2 and so on....
    because first element is y and second is x and question says y

    @39:30, In current example of 3 varible nested quantifier, i.e. x + y + z = 10, we can say that, from all the options, the option that has ∃z at last postions will be True, b/c we can choose any one value for z from domain and get 10.

      @@cosmophile8218 As per the Q , y is the first coordinate in the ordered pair i.e., (y,x) since the outer loop represented by Y runs first.
      Since the general form of an ordered pair is (x,y) hence the positions interchange making it (1,1) , (2,1) and so on.

    Sir ek doubt hai....
    53:40 par
    ∀x ∃y ∀z mein ham x ki sabhi values k liyea check krege ki koi ek y aisa hona chahiye jiske lea sabhi z dalne par true aye
    Yani ki sabhi x ki liyea check krna hai to ham x1 k liye krege fir x2 fir x3....... Xn
    To maan lete hai ki x1 k liye check krte samay hame y ki ek value mil jati hai (y1) jiske liye sabhi z dalne par true ata hai..... (Maan lete hai ki aise values mil gy..... Actually nahi hongi, par man lo hai)
    Ab ham x2 ke liye bhi same krege.... To is baar kya ham y ki koi alag value le skte hai.... Ya y1 he lena pde ga.... Means y ke sath there exist hai....to kya x ki sabhi values k sath y ki same value leke prove krna pde ga... Ya alag alag le skte hain jise x1 k liye y1 aour x2 k liye y2........ And so on??

    @53:00 Sir, on question no. (g) while solving by short cut you said that y must be independent from z that's why it is false. but on question no. (d) also we can use short cut and declair that x must be independent from y that's why it is false but you said that is true. Please, sir can you clear my doubt. Thank you

    • @pavansingh8089
      @pavansingh8089 Рік тому +3

      In option g) by using shortcut method y must be independent on z but in equation (y=10-x-z ) , y is dependent on z that's why it's false.
      Now, in option d) x must be independent on y but in equation (x+z=10-y) , z create problem in making dependency of x on y. Hence, it's true.

      @AmitKhuranaSir  3 роки тому +8

      Part 6 is saying
      For every y their exist at least one x such that x>y that is y is less than x
      Since domain has only 3 values so one by one check all values
      When y is 1 then x can be 2 or 3
      When y is 2 then x can be 3
      But when y is 3 then we can't find x
      So this is false.....
