Your teaching way is pretty good sir 😊. No one can forgot your lecture 👍. Keep making these educational videos for us . Thank you sir for everything 🙏.
Sir hajurle even powered function kahile one-to-one hudaina bhanisyo 19:40 ma tara what about A=set of positive integers B= set of square of positive integers f:A--> B is defined by f(x)=x^2 ? Let x1,x2 E A then f(x1)=(x1)^2 and f(x2)=(x2)^2 Now f(x1)=f(x2) implies, (x1)^2=(x2)^2 implies, x1=x2 which shows f(x) is one-one (Alik bujina sir maile please help)
You're correct I'll discuss this in detail in one to one and onto function. Yaha ailay real number maa Vanna kojeko ho. Special sets like positive integer,natural number etc haina... We are here dealing with real number as a set for both domain and range.
Tme domain and range ko size batai Hera Even powered function maa domain is entire real number but range is positive real number including zero only. So this is never one to one. And this fact is self understood that we are talking about real number as set. Special sets will be dealt in respective question. I have repeatedly spoken here that we are talking about real function and set hamro R ho.
Hudaina.. You are just putting x=0 only, we can put negative values of x as well. That's why domain = (-infinite, infinite) Put x= - infinite then y= - infinite. The solution of video is correct.
I was reading this since last one month but l was not able to solve any question but when l watch this video l got concept and now l am able to solve any question
The function you're talking about is one to one, number of elements domain and range will be equal for this as one input as domain gives one output as range
You're correct. But if function is one to one, elements of domain and range are equal. As we know inf-3 is again inf, so directly we can't say number. You're correct that [0,inf) has more numbers than [3,inf), but in case of one to one function, we count only associated numbers, so domain and range have equal elements.
sir please analytical geometry ko pani class banaunu na hus sir . mero teacher le fast padhaunu hunxa so hjr le padhako malai sjilo lagxa. please chadai banaidinu hus?
He is really a best teacher in whole nepal just must of the stds dont know about him. Sir keep hardworking we will support you .
@@ssgaminge RB smart class is good but not better than iraj parajuli class❤
@@ssgaminge no comparison he is best in his own way the concept he gives is the best,, just like he says lifelong tattoo nei hunxa brain ma
His confidence gives me confidence. Much appreciated. Thank You, sir.
I would like to prefer to stay home and watch your video instead of going school
.
amazing content sir
you have divine power of explanation
thank you
The word "Divine Power" sounds different nowadays.
you teaching skill is excellent not the way you learn but the way we can learn

Thank you sir for your confidence But all theory of functions should be taught in class 11
your teaching style is firstclass
sir your explanation is so clear and understandable , thanks for this.
Best or must good study and teaching...sir❤
Sir next video please amazing 😍😍love you sir
Really good 🎉
Your teaching style is very realistic
I got my finals in a month and this video helped a lot. thank you sir...
Nice teacher in my life
Mero pratik la vaneko you’re the best teacher rye so I’m here 1 day before my board’s exam🥹

sir you are ever my best teacher in the world.❤️💛🤗
Wow its amazing thank you so much sir ..but i have one question hamle directly domain rw range lekhde hunxa ?????
Wow❤❤
you are great sir
Thanks sir 🥰🥰 very helpful

so good sir thankyou so much
It's amazing 👍👍👍
Nice video

sir class 11 ko new optional math ma k padnu parchaa
Sir hajurle even powered function kahile one-to-one hudaina bhanisyo 19:40 ma tara what about A=set of positive integers B= set of square of positive integers f:A--> B is defined by f(x)=x^2 ?
Let x1,x2 E A then f(x1)=(x1)^2 and f(x2)=(x2)^2
Now f(x1)=f(x2)
implies, (x1)^2=(x2)^2
implies, x1=x2
which shows f(x) is one-one

Sir yo function k y=3x+2 wala ko k range (2, infinity) hunna ra? Reply plz
Hudaina.. You are just putting x=0 only, we can put negative values of x as well. That's why domain = (-infinite, infinite)
Put x= - infinite then y= - infinite.
The solution of video is correct.

Language lekhnu parxa ki nai sir domain range lekhda
Sir I think domain is not always greater than range in all cases ...
For function y= sq.root(x-3)
Domain is less than range as x>=3 and y>=0.
The function you're talking about is one to one, number of elements domain and range will be equal for this as one input as domain gives one output as range
@@iraj_parajuli domain = [3,inf) and range= [0,inf)
Here domain elements are less than range...
Isn't it?🤔
Thanks for your reply❤️..
You're correct. But if function is one to one, elements of domain and range are equal. As we know inf-3 is again inf, so directly we can't say number. You're correct that [0,inf) has more numbers than [3,inf), but in case of one to one function, we count only associated numbers, so domain and range have equal elements.
