1. Use the link above to play the video which are under “pen cast” folder named as,

“Math 560 Chapter 17.pdf” for problem 17.4 a

“Math 560 Chapter 18.pdf ”and “Math 560 Euclid’s psotulatesast.pdf”for problem 18.1c

If you look at the calendar in the syllabus, you will clearly see that I only assigned 18.1c. The Pencast explains how to show something is a 2 manifold. It involves verifying the postulates just like you did on the sphere 

2. If you do not know to play those go to the pencast folder, watch the video named “ How to play a pencast” and follow the instructions as per the suggestions on the video.

Problem 17.4 a

Problem 18.1
