- In this video we have discussed counting of functions. counting number of functions is important. We also discussed total number of functions from a to b. total number of functions counting is very easy. So many exams ask the question on total number of functions between two sets. Most of the time they ask total number of onto functions or total number of onto functions from a to b. so we should know total number of onto functions formula. they can also ask total number of one one functions. total number of one one onto and bijection function we can find easily. So lets start total number of functions from set a to set b.

Sir not only your videos help me in understanding the concepts mentioned but also I learn how to think for the Maths related competitive exams. Thankyou so much.
प्रिय शिक्षक, मी आत्ताच तुझ्याबद्दल विचार करत होतो आणि अशा परिस्थितीत आपण व्हिडिओ अपलोड केला. प्रिय शिक्षक, तुम्ही खूप लांब आहात. आम्हाला आपल्या सर्व व्हिडिओंचा चांगला फायदा होतो आणि तो आपल्या सर्वांसाठी फायदेशीर आहे. धन्यवाद प्रिय शिक्षक. 🙏🙏🙏🙏

Thank you so much sir 🙏🏻
Truly respect 🙏🙏🙏your effort
Thanku sir🙏🙏
Sir, what will be the cardinality of one to one maps from N to N?
Thanku sir
Thanks..
Tnq sir
Plz upload video on point set topology with questions
Sir apki notebook ke pdf mil sakti h pls
Sir, binomial type expression ma - sign kyu araha hai. In onto function
Thanku sir
I was really strugling in these question before this lecture
Sir , explain how those formula's came..
Sir kvs maths k exam hua 18 Feb ko to us type k question ka kuchh help kijiye kon sa book sahi rhegaa
Ratwao na reason ke sath formula bataye
Sir please make a video on the topic mappings with examples...
Sir continuous pr bhi vedio dijiye
Great class sir.......made it look so easy😍🔥
Hello Sir Please make videos on Sylow Theorem and It's Applications
Sir how to prove these formulas?
👌👌👌
Love this lecture.... I am jee advanced 2020 aspirant ✌✌✌✌✌
Same here😁
Sir plz make a vedio....how to prove function is onto...
With example...
Plz😢
Bhut easy hai
At 7:08 the infinite sum goes 1 to n in the backet?
Thanks a lot sir
Just jokin. U didn't gave derivations only told the formulas as it is .
Haha u should have read full comment before giving a heart 😂
Don't worry dear. I am always thankful to each and everyone for appreciation or critisism. Because both will give me motivation. Thanks again.
Lighting problem sir
If possible explain the whole expression!
That will be better I think..
Explain why in case of onto functions we subtract this and then again add something?
Because there are some into function also.
Hope you got it.
Thanks A lot sir. Sir, except m=n=2, can ever be total no. of bijections equal to total no. of functions.??
No.
This legend has cleared my 2 years old doubt
Oh. Thanks for appreciating
Sir real analysis mai phd...sabse acha kis college se hota h..
Proof of formulas ur smjha dijiye sir
Sir pls real analysis ke video bna digia
Sir,what will happen when both sets are uncountable??
Total number of functions are also uncontable
Thank u sir
Thank you sir....
A request, please discuss about the
Number of reflexive, symmetric , transitive,and equivalence RELATIONS on a set....
I will send you the formula list for them
Thank you sir !
Sir ye onto ke liye m≥n ke liye derived kaise huaa?!
Sir at 7:00 how did we get the formula of surjection ?.. please explain this...
Its background is permutation and combination, u can try for small cardinality and verify it
@@RahulMapariBasicMaths ok Sir I will try😊
Great teacher. Thank you very much sir😊
Legends watching this at quality 1080p😂😂😂😂
Sir apki offline classes kha hoti h????
Amravati district Maharashtra me sir mpsc+ Csir ugc net-jrf ka exam qualified h
