week 6

This week we mostly just reviewed more about proofs. The tutorial this week was cancelled.

We were introduced to the topic of floors and ceilings and learned about how these worked in proofs.We also went over the idea of proving things false. To prove somethings to be false, you can disprove them and to do this you can prove the negation. This week epsilon and delta were also introduced to us and were incorporated into some of our proofs. This week I was also told that if we can't solve a proof even if we write what lines we are able to write without the proof we might still be given some marks for the question which is great to know.
Finally we also discussed a bit about a backwards search. This is starting with what you wanted to prove and working backwards to what was originally given,
