CSC165 Week7

This week we learned more proofs. They involves more rules and many other concepts. The proofs covered in this week are more and more detailed.

For most of mathematic proofs, the key thing is to understand the definition we are given.Then try to derive something that has the same form of the definition. For example
In the above example, we have 7(7i^2+2i)+1. We have to see that is the same form of 7k+1, just for k=7i^2+2i. The idea is the same as picking delta wisely for the last week's proof.
