Understanding Linear Algebra Intuitively 87 points by Jagat 1847 days ago | hide | past | web | 8 comments | favorite

 Very cool. I really like the graphical representation. As a 'visual' person that help quite a bit.One suggestion though:Don't use x and y for vectors as those are typically used for individual coordinates in the Cartesian plane. So saying x=(0.75 \ 0.25) is a bit confusing as the intended audience is probably used to thinking of x=0.75 and y=0.25. Or say they would think of translating point p into point q where p would have coordinates (0.75,0.25) and q some other pair of x,y coordinates.
 I feel disappointed when people use light shades of red or green to prove their points - it makes it difficult for color sensitive eyes to grasp the visuals.
 You mean color insensitive? Or just colorblind./my pointless comment for the day.
 "Intuitive" is completely dependent upon audience, in this case.

 Even the proper use of the nipple has to be learned - if you start a baby on a bottle it often won't use the nipple correctly: http://www.askdrsears.com/?q=topics/breastfeeding/common-pro...
