Using Symmetry as a Sketching Aid

For some reason, you always make me happy when I'm doing math (which is a rarity for me). Thank-you for being so passionate about what you do and your excitement is evident!

great video! really had me understand some points I didn't notice or thought were not important. Also brought a big smile to my face so thank you for that.

At 09:11, you actually mis-plotted your point.. It looks like each row on the x-axis represents a value of 3, so it should have been one row up.. And vice versa with the second plotted point.
