@@MathematicsTutor I think a circle is many to many. The a domain value x produces multiple y values and a range value y can be produced by multiple x values
you dont worry sir! i will make ur videos popular by saying to my friends and saying them to say to others like that goiinggg on and i will do my level best
If one to many relation is possible in a data, but it makes a situation in which there is no repetition of primary and foreign keys, then will it be one to many or one to one? Anyone??
@@MathematicsTutor no sir, I meant suppose if a relation is one to many, can that relation btwn 2 sets have elements which also follow one to one relation?
Yes, it's a possibility that there can be some elements in the two sets that can have one to one relation but if we have even one relation of many to one or one to many then we don't call it a one to one relation.
Highly appreciate that! It is difficult to get them on top of search engine. I really don't know how to do it. I don't even have a web-site to direct my viewers. I'm happy that some are able to appreciate! hope that many will join. Thanks for your thoughts!

Best explanation forever
can some tell me the equations for the relation like y=xt3 for each of them please
Can you please elaborate. Did not understand the question. Thanks
the equations for the 4 relations@@MathematicsTutor
I think you should go through this video again
Thanks sir 🙏🙏
But i thought second one is many to many
No, it is on to many. Thanks

I agree this video is incorrect I would not trust it also he says y=x^2 is a one to one when it is a one to many@@matthewjohnstone7324

WOW! Thanks a Ton! I will make videos for you whenever you need. Feel free to post questions. Thanks Sudha!

y=x^2 is many to one and not one to one
How
Oh wait is it coz it’s a parabola ?
@@santanzotss yes
Yeah, that's true.
Not many to one, one to many. A horizontal parabola would be many to one!
No.1 thanx
Thanks for appreciation
@@MathematicsTutor do you help me
Nice
Can one to many and many to one relation have elements with one to one??
No. Relation is defined for the set of element. Even if one of them is related with many, it is not one-to-one
Thanks
