However, Cauchy observed that the stress vector T {\displaystyle T} across a surface will always be a linear function of the surface's normal vector n {\displaystyle n} , the unit-length vector that is perpendicular to it.
Some do and some don't. A Nintendo Wii costs approximately $250 (the price range is $160-$380). <br /><br /> Don't forget that, in addition to the Wii itself, you have to buy games and controls; that'll cost an extra $50-$100.
The Wii U's Nintendo Network is not entirely free. According to a Wii U support page, parents or guardians must pay a one-time fee of $0.50 to create a Nintendo Network account for children under the age of 13.OL Nintendo is not what they used to be, they've turned into a real joke, LOL at all those fanboys that said this network would be better than PSN or XboxLive. Buy the system for $300 and oh wait... one more charge of 50 cents because Wii U aren't for minors.
