Amen, Broseph.

[@durnibardebnaath]

thank you, madam your way of teaching has been a real tunnel, to me passing the exam on a single night. .

[@sadiasiddique6254]

Thank you for such a clear explanation , way better than in my course's slides

The terms that was used was very friendly even I from the Philippines can understand

[@islombekabdurahmonov1115]

thanks alot. very helpful and great video i had ever seen

[@inadaizz]

All of your videos I have watched thus far have an electric ohmmmmmmmmmmm sound to them. idk I feel like when you're going to upload this much content it is probably worth looking into. Maybe you have by now idk. But you have a nice American accent and I really need to learn this stuff haha. Thank you for uploading these. I truly appreciate you educators who upload content that is free an accessible to all. You're the best. ☻

[@SawFinMath]

I know. It's very annoying. I wasn't aware of it when I was recording. I'm upgrading my equipment now.

@@SawFinMath You can often use a program like Audacity to remove or subdue the noise, pretty easily.

@@jfriz6900 Thanks! I just downloaded that the other day but don't have a good video editor yet. I am cheap and usually export from power point and upload. I appreciate any and all advice!

Thank you.

How are these free when I'm paying 2 grands at a university for the same course? Thank you so much.

[@theolav12]

Shouldn’t it be preimage(s) and image in the last slide? 5:25

[@SawFinMath]

Do you mean instead of domain and codomain or range? The terminology means the same thing. That is why I include domain and codomain as well as image and preimage in the practice questions. You should know all of the terminology so that when you are presented with a question, you know how to go about it.

[@user-du9zt5rp5x]

@@SawFinMath I think he/she meant that it should be written as image instead of image(s) and preimage(s) instead of preimage

[@neloyislam4002]

what is codomain

[@coryanders6328]

One thing that is not really adequately explained is codomain versus range. The range is obvious because you can see that. They are the results of the functions of x1,x2, etc… that is explained well… but the way it’s presented in the video, the rest of the codomain is just being pulled out of thin air

[@Oddbeingchaff]

Please explain how you would do the codomain then, I'm not challenging you, I just rely on these videos quite a bit and I would appreciate an explanation 😅

[@Carrymejane]

There is other resources that teaching us about this things​@@Oddbeingchaff
