Set Theory: Types of Sets, Unions and Intersections

We've already learned a little bit about set theory when we first started using interval notation. Let's expand on this a little bit to include sets that merely list some elements, so that we can understand how to find the union and intersection of two sets. This is good notation to know right here!

Check out "Is This Wi-Fi Organic?", my book on disarming pseudoscience!

People like this are underappreciated and lifesavers for students.

ur doing a series on SETS. Great, run with it. I like the way you explain things.

IDK why we didn't learn this in middle school it would have fit in there. Makes me feel like my courses were watered down

Hello! SPOILERS!



For checking comprehension, Q3, how did you derive union: (-∞, ∞), this is the only part I got wrong.
Thank you!

[sneakylemon]

which videos would you recommend for a more in-depth look at set theory including subsets and such? I'm starting with linear algebra II this year at uni. Your videos helped so much last year! Thank you so much!

i started this video in double speed and i heard "It's Professor Dave, let's learn about sex" and i was confused

[gopalsoi]

Really i feel very bad. If we would have this type of explanati on. We would have achieved higher studies. By listening this, i want to study high school again

[Quran.And.Science]

Very good. No one can beat you professor.

[claressalatia]

I was very confused while watching the video number 75 from this playlist because this wasn't explained before hand..

[truesanatani]

Why does it say.." he knows a lot about consistopp.."

[nicholaskong]

I was just thinking seeing numbers being used made it easier for me to understand union and intersection.

What's the lyrics of intro
Can anyone tell????

[akirabinismael]

is there any difference between bracket "( )" in coordinate system and in set theory? or there just same symbol?

[yulnikita]

Will we ever be using algebra in real life? I am feeling some resistance in learning it for school because it just feels like knowledge I will never need to use.

I had a doubt in this chapter as my friend says Sets is very hard though it sounds easy.. BEWARE math soon is gonna b interesting for us
