Hope this makes sense:)

Great respect to the math sorecerer. I was hired by an evil company to do finance after i studied maths but I lurk the deeps of the web to study mathematics in my spare time. and the math sorcerer is a priceless channel. love what this guy does. Hopefully i can make it so i can go back to studying math full time :'(. Even watching the beginner videos get me nostalgic of my start in mathematics.

Injective: everything in CoDomain hit at most once. Surjective: at least once. Correct? If so that's a great way that you put it (4:52)

i need help, is being bijective; mean that the function must be strictly monotonic and continuous over an interval.or just striclty monotonic without mentioning continuous???
and thank you

I don"t know why but the instructor strikes me as Jeff Bezos with hair

I think the domain should be the set of strictly positive real numbers R++ Min. 2:45.

Are you teaching mathematics in the janitor's closet?

[DANGEN-KENYA]

The vibe is killing men, , , , I wish lecs wd be like this

[willFALL]

Its people like you who I wish to go to a bar and drink then casually bring up a math problem and start scribbling some proof on a napkin

[grothendieckriemann]

what a good vibe in this clasroom. I wish professors will be more this and less angry.

I feel like I'm watching someone teach illegal math in a basement somewhere.
