where have you been i've been searching and watching so many videos and longer videos but you just killed it in 5 min thanks a lot from the future of Sep 20, 2014
my teacher defined injective as "if it takes distinct elements to distinct elements, ie if x,y ∈ A and f(x) = f(y), then x = y", that now only makes kind of sense after i understood it from your video, so thanks!
nice, thanks. so am i right to sya that words like "injective surjective bijective" describe the co-domain (or the range) and the lef-unique and all that is relating and relevant to the domain?
profs stay making this stuff 100x harder than it actually is
simple , fast and perfect keep saving us
np:)
Thank you master!! You just saved my life today! Never seen such a clear and to the point lesson.
I learned so much is such little time. I’m great full for people like you!
Awesome 👍
been sitting at a lecture for one hour trying to understand this and now it took 5 minutes, i love you
Literally, this is how teachers should be explaining things - with simplicity. Thank you!
glad it helped!!
No numbers were harmed in the making of this video...
haha yeah
....and no neurons were harmed in the viewing of the video either!

The last Math teacher Jedi. May the force be with you
thank you!
FINALLY , you saved me a night of headache
After 9 years I finally had a trick to remember this.
Thanks.
By far the best and easiest to follow video on functions

you are a great teacher.
short crisp and just to the point !! thank u !
Welcome!
wish everyone explained things as clearly as you! :)
Hypno Kitten awww thanks! I'm glad it made sense!

Honestly, Understood
Thx sir....🔥⚡
Thank you!
Fantastic video, been struggling with this concept, despite being simple.
you made it look so easy, legend
Thank you,I love you so much 🥺🥰😭❤
i swear... textbooks plz just make it this clear and simple
Thank you Sir for this type of very easy and understanding explanation.
Great video! Thanks a lot!!
You are welcome!
It's just awesome.
Thank you so much The Math Sorcerer
It hit my brain so easily. :)
:)
such a great video !Thank you
You're so welcome!
Too good .... Astonished .... Keep it up ...
glad it helped!
Thnks....... It was very Helpful👍
I love this explanation thankyou ,it was good quick revision for me❤
Tackar så mycket, very nice and simple. Please show us more, Gandalf of mathematics! :D
really nicely explained thank you :)
Thank you!!
It was a good effort !!! Keep it up!!
Very good, thanks so much
RaafieNL Np, I'm glad it made sense!
Great short explanation :)
bartdacaveman thx!!
So you can have bijective where some in the domain don't get mapped?
xcellent and precise
Thank U for this excellent explanation
np!!!!!
nice, thanks. so am i right to sya that words like "injective surjective bijective" describe the co-domain (or the range) and the lef-unique and all that is relating and relevant
to the domain?
Thank you so much!
EXCELLENT!
Thank you!
I know this is an old vid, but I'm not understanding what the co-domain is. How is there something that's an output w/o an input??
that is perfect
glad it helped!!
Cannot thank you enough
His definitions are so hip.
+Mi-lee Wilson lol thanks:)
thanxs
beautiful
HIS VOICE IS SO
+Meghana Kandarpa LOL yeah I know, terrible voice:)
not surjective and not injective looks exactaly the same
