User: what is covarient tensor?

Weegy: The simplest use of these terms in math is to distinguish two ways of defining a vector in terms of coordinates. If I speak of the slope of a plot of l and I could as well speak of the gradient of the hight of that plot from point to point. [ A point here belongs to a 2D space with latitude and longitude as coordinates. I could speak of the gradient of any field that ascribes a number to each point in the field. If I deal with weather patterns I will likely think about temperature and pressure gradients. These gradients are vectors, they have a direction and magnitude. From Wikipedia: In mathematics and theoretical physics, covariance and contravariance refer to how coordinates change under a change of bases (or coordinate system). Components of vectors transform contravariantly, while components of covectors (linear functionals) transform covariantly. A tensor (T) is usually followed by subscripts or superscripts a,b,c,.... If they are subscripts, then it represents a covariant tensor. If they are superscripts, then they are contravariant. It is possible to have a tensor with both covariant and contravariant components. If you have a vector represented as a tensor T, then Ta is the conjugate transpose of Ta, for instance. Hope this helps! ;-) http://answers.yahoo.com/question/?qid=20090613031632AADP6IK ]
