maths , sets doubt
i just started 11th btw , so i might sound very dumb asking this
well , generally in set builder form , we write the common property of each element of the set right
what if the elements of the set have nothing in common >

Note for OP
+solved @user to close the thread when your doubt is solved. Mention the user who helped you solve the doubt. This will be added to their stats.@nermal xD I think Phys is being pinged by default
@Apu
A set is only defined if the elements have something common property other wise it will not be set
It's not dumb, Cool that you asked
See set builder form is one of the methods to denote sets,
A way to represent one in very nice, convenient way
Now sets can be made of unrelated things, Sets can be made of any things that you want, but in case they're not very related, it may not be possible to represent them in the set builder form
thank you :)
can we represent
G= {11,19,141} in set builder form ?
Yes bro
well could you tell the answer :)
G is a subset of set of real nos
mm thanks
G={x:x is a real number} ? doesnt seem much specific to me 😕
or
G={x:x is a natural number less than 142}
mm , could you give some examples of roster sets that cannot have set builder form? :)
i will try...but i dont think so
No i t means G = {1,2,3...141}
yeah mb i should have written subset as well
Np
i still didnt get it 😔
Tell me where you are confused
There would be no easy way to define this set using a set builder form , but you can deff make something , but dw that type of sets which doesnt have a visible pattern wont be asked to make in a set builder form
i can try to make the set builder form of G if you want , i can define some function using the numbers
Yeah its representation is beyond JEE
Btw these all are semiprime nos
using this would be a little cyclic but this is one of the ways you can represent that as set builder:
G = {x : 8k-5x+15 = 0 , k ∈ {5,10,86.25} }
but you wont be ever asked to convert something in set builder form unless there is a visible pattern or series
Very nice definition but to we have to also define K set that means we are stuck in a loop
yeah exactly what i meant by cyclic set but yeah it is what it is
maybe it can be represented on some nice function which have nice solutions , i will try finding it later
lmfao
@zero you good? shall we mark this one as solved?
Yep ig
