Description
This is a course on PROOF WRITING with Sets:)
This course starts with some VERY BASIC definitions regarding the theory of sets. Some simple examples are given at the beginning, but soon after, the PROOFS begin!!
Important Note: A formal prerequisite for this material is an understanding of mathematical logic. However I have tried to explain the ideas from logic as they come up in the proofs.
The best way to learn to write proofs is to watch someone else give careful proofs and then try to do it on your own.
This is the MANTRA behind this course which is full of beautiful 100% correct well written proofs!!!
Basically just,
1) Watch the introduction videos if you need to. These cover the very basic things that you should know regarding sets.
2) Watch the PROOF videos in ANY order. Take notes, try to understand them.
3) Try to do the proofs on your own! If you can't, watch the video and cheat and try again.
It takes A LOT of effort to learn to write proofs like the ones you see in these videos, so don't feel discouraged if you find it difficult, it is supposed to be tough.
This is an EXCELLENT course for anyone who wants to jump into proof writing. I hope you enjoy watching these videos and working through these problems as much as I have:)
Who this course is for
Anyone who Wants to Learn How to Write Basic Proofs with Sets
