Hello Jiaqi,
We've added files with the solutions to the HW assignments in the class site. Each file contains both the answer and a detailed solution to each of the problems assigned for HW.
Please take a look at the files and let us know if you still have any questions on those problems,
David
I don't see any files. It only gave me the answer.
Inside each week you should fine (under the assignment) files such as "Mathematical Wisdom Chapter 2 Excerpt Solutions File". These files include the answers but also explanations to the problems.
If you still have questions after reading these explanations, you can ask here in the forum and we can provide more clarification.
