Algebra 15 - Functions

Functions can be thought of as mathematical machines, which when given an element from a set of permissible inputs, always produce the same element from a set of possible outputs.

These are by far the best maths lessons I've watched. I wasn't getting the whole ordered pairs, binary relation thing or even why it's there but after watching these videos, the math now seems plain and obvious, almost intuitive. Thank you and please continue. These videos made a big difference to my understanding.

thank you! I think you have the best math videos!

These lectures are, by far, the most clearly explained lectures I have ever had. I am a first year physics student and although I *thought* I knew a lot of the technicalities in mathematics, these really do explain EVERYTHING. I never even knew the range was the subset of the codomain. Thank you for these videos!!!

these are wonderful tools to recover mathematics I have studied more that 40 years ago and clarify lots of uncleared concepts. Let's hope that this project will continue opening new viedo sections in the infinitesimal calculus, triginometry etc.
Congratulations and thanks a lot to the developers!

Really fun, How can I make a similar video. I mean which sofware you used?

[domzyko]

wow . because of this i might jus love math . it's not that hard at all

A function can only give one output per input? But what about f(x) = sqrt(x)?

TQ bro for giving us good program, keep it up.

[eimaldorani]

Well Explained. Thanks.

However, I'm wondering about the tobacco smoking pipes.
tobacco smoking pipes!? Are you promoting tobacco !?

[tasos_plat]

this is the best maths show on youtube! keep going! im looking forward to your videos on calculus

[SOBIESKI_freedom]

Thank you for this installment. Looking forward to more :)

We really don’t talk about co domains in High School for some odd reason

You said that each input will have a unique output value. But in 4:20, You have shown that Tarzan, Jane and the boy may like the same fruit. You also said that it is a function. How is that possible?
