Gradient concept. Every fashionista needs to know what a gradient is. Modern gradient design

Gradient (vector) Gradient(from Latin gradiens, gender gradientis - walking), vector, showing the direction of the fastest change of a certain quantity, the value of which varies from one point in space to another (see. Field theory). If a quantity is expressed by a function u (x, y, z), then the components of G. are equal to ═G. denoted by the sign grad u. At a certain point, the geometry is directed normal to the surface of the level at this point, the length of the geometry is equal to. The concept of geometry is widely used in physics, meteorology, oceanology, etc., to characterize the rate of change in space of any quantity when moving per unit length in G. direction: for example, G. pressure, G. temperature, G. humidity, G. wind speed, G. salinity, G. density sea ​​water. The g. of electric potential is called electric field strength.
